Yeah Bill was surprised to see the rubbing too. I don't think its a big deal (as you said) but since I have the ability to fix that stuff, I'm having the cover milled.
There is a local machine shop that I have a connection there and had asked for them to go through the heads. This will be their first 3800 set but the owner has done many high hp SBC and BBC engines making 700+ hp. He does very good port work from what I've been told. So I ended up having him tank the heads, magnaflux (yeah, there was a crack that he found and is repairing), performance valve job, milling the guides to accommodate the .577/.592 lift, and port/polish the intake and exhaust. Intakes will be gasket matched but he plans to do extensive porting on the exhaust side but will keep the "d" shape of the ports.
Just going to be running a 7/8" chain with 2.93 gears. Sold the 1" already.
