How to figure out your C/R ???

[Relix]

IS there anyway to figure out your C/R without removing the head?? I recently get a set of Skunk2 high compression valves installed in my head and wanted to see how much if at all they infact raised my C/R.... Is there any way to gauge this?

Find out how much more volume the valves take up in your combustion chamber compared to stock, redo all the math... simple.

werd- basically, do what cal said, and then alter the head figure here: http://www.c-speedracing.com/howto/compcalc/compcalc.php

volume / chamber volume - piston dome displacement = compression ratio
