Cometic - Gen 5 LT1 / LT4 Head Gasket 4.100" Bore With .040 Thickness

You need 2 for a full set! 
The Cometic .040" Head Gasket is an upgraded quality gasket that is a great choice for a variety of builds (including forced induction/nitrous) that are also wanting a small bump in compression. With unmilled heads, this gasket works great with SS1-SS2 camshafts. May require flycutting for the SS3 or higher. (We always encourage measuring PTV clearance when running aftermarket gaskets with an aggressive camshaft.)
