This may help:

http://www.csgnetwork.com/compcalc.html

Can someone please provide the average head CC on a stock head? I had it in my notes and can't find it. Thanks!
Thanks fatjoe, that's the calculator I have been using, using compressed gasket tickness .6mm, -1mm above deck, playing with AP1 & AP2 values I came up with this 11:1 with the F20C 9.5 CR mahle piston.
Since we don't know the exact values of the CC we can only extrapolate from the total CC values given from that software.
I came up with 52.31CC for the AP1 & 55.76CC for the AP2, those are total combustion chamber values.
If I miss something I would appreciate it if somebody pointed me in the right direction.
Cheers

its approx 52.5cc there should be no differences between ap1 and ap2

I have never measured an ap2 head, but the last one i saw looked exactly the same as the ap1 head that was next to it.

Add about 2.25-2.5 points of compression when going from ap1 to k24 crank.

With the super short rod you will want at least 12:1 compression

Thanks for chiming in, are there any options on the rods, ie; big end oil squirters, pin force feed oiling, etc?

No we do not offer forced oil feeding on the rods.

The oil squirters have nothing to do with the rods. The rod will clear the stock squirter.

Your problem with clearance will be the piston design. If it is a regular style CP piston, it will fit no problem. However if you run another piston, of the piston goes into a x-forge design, you will have oil squirter issues.

Don’t forget that the numbers are for the total combustion chamber volume, ie; piston volume + gasket volume + head volume.
Same head & gasket volume but different piston volume, hence the difference in CC’s.
I don’t know the exact volume of the head, but yes they are both the same (AP1 &2)
I think somebody did CC it and posted the number but I can’t find it.
Wiseco posted 52.5 cc on their product page.
I know I can increase the CR due to the dwell time at TDC, however I want to run 91 octane.
Why are you saying at least 12:1 CR? Fight the loss of hp due to the increased friction?
I was thinking somewhere 11.5:1 on 91 oct…

Yes, the piston skirt is the issue, thanks for the info.

do these rods allow you to use the f20 pistons instead of h22 pistons?

That's the whole idea!

just making sure, i thought they were just premachined to fit the crank/ milled down h22 rods

what pistons would be ideal for 93 octane?
