The compression needs to be set to match the cam, if you don't do that, you won't get the desired results.

So the 585 would be a better match than the 259 at the advertised 9.9 the screamin eagle kit has. Correct?

Perfect would be the 117 kit but with 92cc CC and 0.030 head gasket.

And how would you know if the deck height is an unknown?

G’day y’all,

I am a little confused, so I must be missing something here.  What is a 92 cc CC?

My understanding at the moment is that:
1- CC stands for Cubic Centimeters. Stock displacement in CC is 1802.577 cubic centimeters (110 cubic inches) & 117 cubic inches is 1917.29 cubic centimeters. By my calculations a 117 kit gives you roughly another 115cc of displacement.
2- The intent of the 0.030 cosmetic gasket is to bump compression from the 9.9:1 ratio advertised for the kit to around 10:1 or a tad more which improves performance of the SE 259e cam the kit comes with.

Pardon my ignorance but can someone please explain what I am not getting here.

Cheers Tom

They are referring to the CC volume of the Combustion Chambers in the heads...

Got it all fine just missed one important unknown, how far is the piston in the hole, down? That is part of the calculated volume and does greatly affect the CR

It's physically measured with a burette and a measured amount of fluid usually alcohol,,, check out YouTube "how to measure a combustion chamber"
On the phone this morning, otherwise I would post a link if I was on the computer

All I wanted to know was a ball park combustion area size on the stock cvo 110 head.

Have seen them from 94 to 97cc. Core shift matters.
