Hey guys I'm sending my 243s to TEA for a stage 2 CNC and running an eps cam. The specs are 234/242 .604/.605 112+3 .006 lifts are .283/.291 I had plans to go with a 60cc chamber and a .040 or .045 cometic (I know I need to measure piston out the hole) but TEA suggested a 61cc and .045 gasket what do you guys think? They said the 61cc will be the safer side for 93 octane. Suggestions? Thanks alot guys!

Still would like to know duration at .200. But Looks like the specs TEA gave you puts you at 11.18:1 SCR and 8.48:1 DCR using the .200 value from an XER cam profile and pistons .006 out of the hole.

60cc puts you at 11.33 and 8.58

And 60cc and .040 gasket puts you at 11.48 and 8.69

I don't know if that's fine for 93 octane or not however....I just have a calculator,

I figured the tighter quench of a 60cc chamber and a .040 gasket would be safer than a thicker gasket and a bigger chamber size

you know what to do. go to 60cc with a 40 gasket you will be safe on 93. just no crazy timing thats all...

Ya that's what I thought rob. They probably just wanted to keep me on the safest side and all.
