Not sure where you're at , but the best advice I can offer on the west coast is to contact someone like Dave Mackey in the LA area (Cal) He matches cams to heads and cylinders. He offers a pkg deal where you send in your stuff to him and he works his magic on it. I've said this on another thread somewhere, can't remember which one. At one point before the V-Rods started dominating the drag stip Dave Mackey was the head guy for 7 out of the top 10 AHDRA top fuel racers. He also grinds his own cams with aggressive profiles, but easy ramps so you get good strong performance but not the wear and noise issues some high lift cams have. Carl's Speed shop in Daytona is superb as well. The important thing is to match your parts so going with a sole source on Heads, cylinders, pistons and cams is your best bet IMHO

Regarding the gear drive noise: with  the Baisley LMR-02 oil spring the noise isn't too bad , also did the S&S reed valve breather (reduces blow by and increases mid range hp). At idle you can hear the whine , but it isn't annoying. As soon as your rolling the bike is a good bit louder than stock so it doesn't matter.

Bagger1 you say the bike runs like an old whore now with your current set up. What exaclty does that mean, runs rough, pops and misses some etc?
Or does it just smell bad when you ride her?
Seriously though did the work done make it less undependable starting and running bike?

No old whore just to me means not subtle. Goes like stink ! All good.
I just road a friends stock 03 SE Road King very nice bike,but well just not that exciting. As for reliable I ride between 20 and 25 thousand a year.
The only negative is fuel consumption down 20%.

Thanks for the info guys.
Just ordered everything from Zanotti HD.
Super prices on the stuff hopefully they got it all in stock.

I went with the SE performance heads, SE257 cams, adjustable push rods and SE air cleaner kit. I also ordered a set of the D&D fat cats 2 into 1 exhausts with the ghost pipe from the group buy section here.  Hopefully all that along with the 1550 kit with flat tops already in the bike will net me at least 90+ HP.

One last question whats the deal with the cometic .030 head gaskets?
Is there a HP advantage there or do they just lower your compression some. With the flat tops and those heads it looks like my compression will only be about 10:1 anyway, not to high. I suppose higher compression may mean more HP but at what cost.  So  cometic gaskets or just use the stock set up.

If anything they the .030 gaskets could increase your squish, but would not lessen your compression most likely raise it when compared to using a stock gasket.   Since the stock gasket is approx .050  you would be bringing the piston up higher by approx .020 for sake of government work.   When they build it they should clay it out to be sure of the squish is in clearance range / spec and than decide whether they need a stock gasket or a smaller one based on parts you have purchased and put together.
