You'll have about the same amount in any set of heads if you include the cost the castings.

117" is the crossover in my opinion and where a set of ported CVO 110 heads come into their own..
Dynos using my heads are all over the net. I do a lot of 110 heads and our Street Pro package is at a price point that is easy on the wallet.
I have attached one that was sent to me and is relevant because it is with CVO 110 heads and is carbureted.  11:1
Scaling is screwed up and I suppose this is uncorrected. Dyna with boarzilla

117 is what I would call a gray line too.

Here is a 117 build, using Don's heads.  It is a very easy to ride bike with smooth power everywhere.  Much smoother than stock, and easier to ride.

That's what we've been getting out of 110s with 103 castings at 10.4:1

fwtw... (Same power, less compression and fewer cubes.)

Nice looking curve nonetheless. That makes them super fun to ride when the TQ is flat like that.

Ok guys,

No trade secrets being requested, but at least tell us what size intake valve is needed in the round hemi CVO103 head used on big engines.

Don't know. I've never done a set of those. I use the bath-tub head on everything.

Matt,
 I assumed [wrong] that when you referred to 103 heads, you meant the hemi CVO103 head. Late bathtub 103s, I take it now.

Thanks

The quench pads need to be flat (always) if performance is the goal. Not a fan of that angled stuff unless it's a
nitrous application.

Quench area, the SE 103+ head has very little and is a perimeter band, the CVO 103 head same but less of a band. Of course either gain a little with the larger bore and/or milling. The CVO 110 head and it's derivatives all have a lot less quench area than the bathtub but have a little area on the sides if someone wanted to put in Singh grooves, never done them on these castings.

Easy, easy.....

Just a hack here, but I have had absolutely wonderful results with the grooves on flat quench heads, car and bathtub Harley [and flatheads]. Wanted leaner afr, less timing, less octane needed. I realize, arguing about them is like arguing about religion, or maybe gapless 2nd rings LOL. Don't bother.

I'm sure that there are slanted quench combos doing great, but it scares me. It seems to me that a 4.060" - 4.125" bore under the 103 CVO heads' little quench ring would/should allow for decent quench action.  If I found a set for cheap, I'd try them.
