Well decided to take the plunge and vary a little bit from my original plan.
Doing a set of MVA heads, 10.5 pistons and 259e cams for an early Xmas present ( like the bike itself wasn't enough lol) .
Should be tuned and ready for pickup within a week.

Originally had a set of S&S .583's slated for install, but like a dimwit when I installed the exhaust a few months ago, I over torqued one
stud, and last weekend it snapped on me.  Then like an even BIGGER dimwit I managed to snap the easy-out off inside the stud.

Figured the heads gotta be pulled anyways, may as well do the work I had planned for winter now, albeit with different parts.

Regardless, should be a solid combo, looking forward to posting the results later!
Sadly with the buggered exhaust stud,can't do a "before" run, but figure there's been enough of them posted that should be able to get a
good idea of the gains....

Gram,
Have that stud and EZ-Out removed on those heads, and set them a side for a future project.

if you were looking @ the .583`s,now looking at the 259`s,you do realize the .583`s are a low end & mid range cam & the 259`s are more mid & upper RPM cams.make sure you know what you want

Right on, Kirby... I'll vouch for that! They are definitely mid- to high-RPM cams. I love my 259Es, but with 246/250 degrees duration and 31 degrees overlap, they need RPMs to make power. They are not for engine-luggers, but they run very strong starting around 2700 RPM all the way to red line.

The Drago's 2-1 pipe I run is a very good match for the 259Es. 10.5:1 pistons would make it even better, plus heads as GRam is doing.

I looked at the specs for the S&S 583 cams. Their 203/262 duration is the widest intake/exhaust difference I think I've ever seen in cams. S&S categorizes them as Softail/Dyna cams.

GRam... what type of bike are you doing this work to?

Yup I do realize the differences in the cams. Only went the .583's originally because they were supposed to be installed about 2 months ago when I got
them. Figured spending close to $50k after taxes on the bike and a few odds and ends was about the end of the budget for the year, so went with a cam that would work
with the stock pistons/compression, yet still be an upgrade vs. stock performance.

Since I've yet to install them, and had some issues where I'm forced to pull the heads anyways, I am going to do a similar build now to the way I intended to all along
over the course of the winter. I tend to rev my bikes more than the "average" HD rider, so the characteristics of the 259 should be awful similar to the Woods 8-6 I had before..

Bike is a '13 SE Road Glide that I run solo about 93% of the time.  Had a very similar setup from Scott @ Hillside in my 103" SG, and loved every minute of it 

Scott, yup I will take it to my buddy that owns a machine shop. For the cost of a six pack or two and he'll have er good as new!!  Those heads will stay stock tho, keeping
all the original pieces around for re-install once it's time to sell the bike in a few years..

The 259 cam is not a great cam by any means not even a decent cam. IT does not make great tw or hp in the 110 we just pulled another out as they really don't do much of anything . I would suggest installing a cam that has a proven track record you will make more power and have a better curve at the end of the day.

[GRam]

Well I'll have an opportunity to find out for myself soon enough...
Guess I'm lucky enough I have the time/patience/money to try different things and see what I do/don't like.
Tinkering around with these is a hobby that I enjoy, so trying a few different combos is not the end of the world to me.
And if I happen to stumble across something that works along the way? Bonus! 

If I have to tug these 259's out and go back to a woods cam say...
I will eventually anyways because I'll be swapping out the stock lifters for some HQ units or some of the Woods directionals..

What do think are good cams for a 110 with a 2-1 pipe and Cometic .030" head gaskets like mine? And do you think it's a good idea to bump the CR above 10:1?

Thanks.

I would do the S&S .570 at 10.0-1.as far as the .583 goes,we use them in a lot of torque bagger builds (buiulds that used to get the .551,but the .583 will carry alittle higher in the RPM range),VERY nice cam set.

Cam wise there are many here is an example of a stage III HD kit with 259 cam it was not running that bad for the kit, I swapped out the cam to our Genesis cam and you can see that it was a huge improvement. A 583 is under that one. The S&S 570 has been another cam that works very well. I am not here to say USE this cam more so to say choose a cam that has a better track record. The CVO bikes will vary as the chambers and heads tend to be all over the board.  The top graph was in STD as I had a printer issue as well the customer had a sheet from the dealer in STD so I was trying to compare the numbers the best i could. SAE on that was about 2 down across the board .

Can compare next week sometime, see how mine turns out then. The characteristics of the 259 suit the style of riding that I enjoy.
They are not my first choice, I wanted to do the woods 8-6 again that I had in my previous 103 build, but these are the closest SE parts I could find to still maintain some of that 5 yr warranty I paid for on my more-or-less $50,000 bike lol.
That being said, if I can come close to matching the 114/118 I made in the 103 Scott at Hillside helped me out with, I'll be a happy chappy.
As I mentioned earlier, revving these things up to make some power doesn't bug me in the least.
 
Could be I'll hate these 259's and be looking to get them out before the month is out. IF that's the case I will go back to a Woods grind of some sort over the winter. For now this combo of parts made sense price/warranty-wise, so I'm more than willing to giver er a go.

Heck if I could get a few deadbeat customers to pay up I could toss a turbo'd 124" S&S at it, with $$ left over for a crate of tires and clutch plates lol..
Finances are driving some of this though. I have fingers crossed, maybe I'm just optimistic?

[GMR-PERFORMANCE]

Good luck with the new build those that I posted are box stock heads, woods 8 can be a good power maker, along with other things as well. Keeping on target , Again I hope the build turns out very well for you and that it meets your goals and budget .

The CVO chamber hovers at 94-96cc's........

[GRam]

Well work is done and had a chance to tear it up a bit...
Feels strong, runs well, some fine tuning needed still as just a tiny hint of decel pop when letting off at high rpm,
but no hiccups/pops/farts when accelerating from any rpm/load/throttle position, so I'm thinking it's fairly close and I'm being a bit nit-picky lol.

Bit of background first.  Scott @ Hillside and I came up with a game plan for my Street Glide last winter. The combo we put together made 113/117, and ran like it.
Real strong motor, loved them TW8-6 and will most likely go back to them at some point in this motor...
Well before I sold the SG to my brother back in June, I took it to the dealer here (who just did my RG work) and it pulled 97/99.

I include the above as it's the only frame of reference I have to do a direct comparison.

Well the RG made 104/111. Disappointing on the face of it, to be sure. According to the dealer, his dyno is 7% to the stingy side compared to Jarz and another shop he mentioned but can't remember,
so in his words the actual #'s are 111/122.
Now not sure about that at all, just repeating what I was told.
That all being said, if my "104/111" is near the same scale as my "97/99" was, then I'm happy guy.

At some point I hope to get it to a second dyno where I had some previous work done to my SG, just to have another frame of reference.
