Going FI need to lower Comp ratio Hey guys I was wondering how I can check and also lower my comp ratio.
I have TSP LS6 heads with a TSP Trqer2 Cam stock head gaskets how do I find my comp ratio.
I was thinking of getting none ported LQ9 heads and a Lingenfelter GT2-3 camshaft 207/220 .571/.578 118.5 CL with a D1SC on 8psi. but I wanted to calculate my comp ratio before doing so.
Im also wondering if I should fork out the extra 800 for patriot heads.
Also what are the best head gaskets for boost?

You need to know the combustion chamber cc's of your heads, and whether you have a stock bore, and stock pistons or aftermarket pistons and their cc's.
Do you have a stock bottom end? If you do, more than likely with the combination of your better flowing heads and an aftermarket camshaft, adding an ATI ProCharger will be too much for your stock pistons. I've only seen a stock bottom end hang in there in a few occasions with the head/camshaft combination. Bob
