Yesterday, I finally got a compression tester extension so I could do the comp. test on the 7M. See with these Heads, you need one of these extensions because the spark plug hole is impossible to get down into to tighten the tester into.

145, 145, 145, 140, 142, 145

I don't think I've ever seen a motor that consistant.... and I am actually amazed that this was a junk yard motor with a blown head gasket!

As for the spark plugs, they are running lean to me. So I will have to probably tweak with the mixture using the AFM. These are OEM spec NGK plugs have around 150 miles on them.
