Q:

I have an LS1 would this gasket be ideal for 243/799 heads? Or would you recommend a better one? I plan on milling the heads 0.2 so I'm unsure on what head gasket to use.

Asked by RONALD on August 08, 2017

A:

This head gasket is made for the 5.3 H.O. or 5.7 ls1. Yes it will work for what you want to do. It's also a high quality gasket and I'm very satisfied.

I ordered Fel-Pro 5.3 gaskets for my 2007 5.3 with factory 799 heads, the Fel-Pro was smaller than the combustion chamber. I ordered these and they say 5.7/H.O. 5.3 on them, they fit perfect. These measure approx .045 non compressed. Hope this helps someone.
