Up for sale is a beautiful pair of 1971 Big Block Chevy oval port cylinder heads. These are GM cast# 3993820 and are dated A-4-71 and A-20-71. These heads are fresh back from the machine shop as they have add the full gambit done to them. They were magnafluxed, pressure tested and then surfaced .010 to ensure that they are straight. New hardened exhaust seats were also installed. The valve springs are and are good to .550 lift and should work just fine with most mild camshafts. The valves are stainless one piece Ferrea 2.07 intake and the 1.74 exhaust. Comes with the new valve springs, retainers, spring cups and 10- degree keepers. No expense was spared when having these built. All you need to do is give them a good cleaning and then assemble and would be ready to roll. Would be ideal for anyone building a 396 or 454. I have way more in these than I am asking for them so my loss is your gain!!!
