I have to tackle head gaskets ive been thinking about champion heads but seen here a few issues with champion heads so i was thinking i might be better off sending them off to be machined. im a little new to the game so im going to ask:if i send my heads to the machine shop is there anything in particular i should ask to be done to them when i drop them off. i here people talk about porting then etc. but truthfully im not sure on all the ins and outs, or am i better off buying heads from champion. i can afford aluminum heads.
