Let's make sure we understand which heads you have. Do you have a set of heads off a 110ci CVO engine; or do you have a set of the SE Pro Twin Cam 110+ heads???

If you don't know, measure the size of the intake valve with a micrometer and tell us what its diameter is.

Better yet, how about a PN? Initial response is that the chambers and valves on any 110 head are too large and, without domed pistons and some headwork, they aren't right for the application.

If DeweysHeads sees this and chimes in, he can elaborate and educate us.

I can't find that PN off hand but will try to run it down. Are the chambers hemispherical or oval? In any event, the chambers will be 95cc or 98cc with really big intake and exhaust valves, I think; too big for a 95" bore with flat top pistons. You would be better off to put them on Ebay and have your stockers worked or swap the 110 heads for as set of '06 or later heads. You are looking at a science project instead of a build if you stick with the 110 heads; they just aren't right for you application. JMHO

Chances are, it'll be mid-upper rpm biased with that set-up.
You be better off, re-working your OE castings, for a dedicated build.
IF, those 110' heads are in good shape, and black, we'd be willing to take them in, towards work on your heads.
We use those on 117"-124" builds here.

Agreed
With a 1.9 intake valve the stock castings flow well and adequate for this build. The OEM head also has a better coefficient of discharge.
