Thank you 64U. CNC Dude is there a common place that these heads crack? I can't remember where the head on my 79 GMC broke but it did not leak oil or antifreeze. Had to buy a brand new head because no one had any good ones used This was in 1987 or 1988. The Chevy dealer had one in stock. The headgasket seeped down the side of the block for 50k+ miles, when I got apart one of the head bolts had broken and the bolt head was laying beside the bolt hole. IIRC I read that you took care of a fleet of trucks with this head? Jay
