I have a set of 1967 283 Cyl. heads casting 520T for sale. The heads have been cleaned, magnafluxed, guides knurled, studs pinned, Ported and Polished, and have been surfaced. The guides have been machined for seals. They are all ***embled and I will get pictures up later. They have 1.840 intake valves(from 305 H.O.) 1.500 exhaust valves. New springs and retainers set up for a hydraulic cam with seat pressure 110lbs. .500 max lift. I did not slot the pushrod holes. I had them flow tested at a shop in Schenectady, NY. The flow figures I'll give the lift followed by cfm. at that lift. Intake-.100-58.5cfm-.200-114cfm-.300-159cfm-.350-179cfm-.400-193cfm-.450-203cfm-.500-195cfm-.550-197cfm-.600-198.9cfm Exhaust-.100-50cfm-.200-97cfm-.300-127cfm-.350-135cfm-.400-141cfm-.450-144cfm-.500-147cfm-.550-150cfm-.600-150cfm. As you can see they are perfect for the average lifts street engines employ. I'm asking $600 and only local pick up please. I also have 2 intake manifolds for the 151/2.5L Pontiac crossflow 4 cylinder engine. I always wanted to put one of these engines in a 23T. One is an Offenhauser Dual Port, and the other is a Clifford with a 2bbl Holley adapter. I'm looking for $100 each.
I have a set of 340292 date coded 1977 angle plug Small Block Chevy heads for sale. They have been cleaned, magnafluxed and have a 4 angle valve job done on the intakes and 3 angles on the exhaust. They come with brand new stainless 2.02 Intake valves and used stainless 1.625 exhaust valves. They will be surfaced just enough to clean them and make sure they are flat. I'm asking $800 for the pair and pictures will be below.
