This is a fresh pair of 3964290 cylinder heads for a Big Block Chevy engine. These were used on 1970 oval port applications. One is dated J 11 9 and the other is dated C 4 70.

These heads are freshly built and have not been used since being completely gone through. They were bolted on an engine and removed before the engine was ever started. The heads have all new guides, hardened seats throughout(intake and exhaust), positive style valve seals, new stainless valves, new springs, Manley guide plates, and new rockers. The exhaust ports have some surface corrosion. I pulled the valves on the chamber that had the most exhaust port corrosion and the seats are still excellent. I imagine the machine work and parts on these heads cost more than the asking price. The head bolts shown are not included. This is a stellar deal.
This is your chance to own the ready to install 3964290 heads you have been dreaming about at a great price. Don\'t Miss Out!The shipping cost shown is for the Continental US only. Alaska, Hawaii, and territories please inquire for a shipping cost.
