Double check my 370 specs (compression)
I'm building a 370 out of an iron LQ4 motor, i will be using the stock crank but i will be going with Eagle forged H beams and forged Mahle pistons with valve reliefs..
these are the ones i bought got a deal ($960.00) Tax Exempt through AutoZone

^those are the parts i have in my possession, i just got my Tick Stage 2 street heat cam in the mail today as well and it looks killer , (Thanks for the help martin)
here is what i came up with by using the Excel spreadsheet
Can anyone double check that i got my input numbers correct? 11.x:1 compression sounds nice if i can do it (i will be using stock mls gaskets) and im pretty sure the parts man told me the reliefs in the pistons are 4cc cuts

I get 10.66:1
Here are my assumptions:
Head gasket bore 3.91"
Volume between piston and cylinder wall above top ring 1.76cm^3 .
Using the above and your numbers I get a clearance volume of 78.341cm^3 (4.781in^3).
