The replacement is almost stock. Does have a curve kit.

Dynoing is done for today. Ran into a snag. Screw in studs contact the rockers when lashing. It is weird as this is not the first head to screw in studs by me. need to take another appr .200 from the boss's. allready took .375 from them.

This is the latest GM casting. I have 5 of them and they are clearly different than any other late model head ever done by me.

They weigh considerably more than other castings also. Plenty of meat. Try more on monday. Tom
