1998 LS1 Compression with 706 heads help
I have a 1998 Z28 with LS1 that has 706 heads millied 30 thousand with Cometic MLS gaskets. Anyone got an educated guess on what the compression is now. It has to have 93 or better oct ane or knocks. I run Sunoco race gas though it with the 93 and it runs great then.
