Can someone help me figure out my Compression ratio Im really bad at figuring this out, i always have been. I think i have figured it out but I'm not 100% sure. Heres what i plan having my set up being
243 heads stage 1 ported by TEA
650. Brian tooley springs
Manley valves 2.02's /1.60's
Comp rocker arms
Ls6 intake
Ported throttle body
Ms3 cam
Mahle forged flat top pistons -4cc
Scat I beams Forged
Im not sure on a head gasket yet which is why i asking what do you guys think my Compression ratio will be on .40, .45, .50., ect.
Any and all help is appreciated !

What cc are your combustion chambers after the work TEA did?
Assuming minimal milling (64cc) and running the .045 gasket to tighten quench and bring compression back up, and assuming pistons are .010" out of the hole as usual with the Mahles on a 9.24" assumed deck, I have you at about 10.5:1 static.
But that is a LOT of assuming, so more finite specs would help!

Depends on deck height and which rod you are running, but yes.
