4 Tech Questions 1. What is the compressed height of a stock GM LQ4/LQ9 Head Gasket? (.054?)
2. What is the gasket bore on a stock GM LQ4/LQ9 Head Gasket?
3. When calculating compression ratio(SCR) what average deck height measurement do you use? (.008?)
4. How many cc's is the dish in a LQ4 piston?(-8cc's?)
thanks in advance

Don't know the answers but just something I figured out recently... the compressed height of your head gaskets can REALLY affect compression. Didn't know that till yesterday. Knew it would affect it but a whole point?
