I know a guy who has a port/polished head for a pretty reasonable price. Everythings still in it i.e valves/caps ect. no cams tho.
He's not on here a lot so let me know, I'll have him contact you.
Also, take your head to a machine shop and have it checked. I literally finished my head gasket two nights ago and thought it was the head too.
Ended up being fine....
