Question for you guys. I am having my block and head machined, and head rebuilt. The machine shop is balancing all engine parts, boring engine block, and all other machine work to it for $325. For head rebuild (I supply parts) he is cleaning head, decking, 5 angle, cuting heads for 1mm over, installing all new valves, guides, seals, etc for $375. This is my first Dsm build and wanted to see if you guys thought prices were fair. The guy is a stud machinist builds NHRA funny car motors, etc.
