Answer This Question


Will this gasket work on a 2008 ly6 6.0lt 4.030 for boost later. Need the .054 thickness because rods are 6.1 vs 6.098. Or do I need not worry about .002. The pistons are also +3cc over stock. stock stroke? Compression calculation with .051 is 10:1. With .054 9.6:1(ish) I research stock piston above deck at .007.... .009 with 6.1 rods. thank you
