This is a set of 3.8 liter GM Pontiac 3800 cast iron V6 cylinder heads. We completely rebuilt & reconditioned the heads by performing a three angle valve job and surface to them. The original cylinder heads that were brought into us were both cracked in their combustion chambers so we actually sourced another set of good rebuildable heads which we call cores. After thermal cleaning and blasting the heads we performed a magnaflux to make sure they weren’t cracked. We then pressure test each cylinder head to make sure they have no leaks. After it was determined that the heads were not cracked and leaking and that they were good heads for rebuilding we machined the valve seats in our Tobin-Arp seat-and-guide machine. We then surfaced the decks of both heads on our AMC surfacer milling machine. The valves were all ground on our Sioux valve grinder. Once all the machine work was completed we assembled the heads complete and then vacuum tested them on our vacuum tester to make sure the valves were all seating on their respective valve seats. We are a complete and fully equipped Las Vegas Machine Shop that can handle all of your cylinder head service and other machine shop needs. Please give us a call or come on in.
