39734487X S.B. Chevy Heads- Rebuilt-Dec 71 cast dates
I have a pair of used completely rebuilt 39734487X heads for sale. Intake Valve size 1.94- exhaust 1.50 Valve Size. 76 cc chambers. Heads were magged for cracks, new valve guides, seals, seats ground, checked for flatness, factory springs were reused along with exhaust rotators. These heads have cast dates L-22-1 meaning- Dec-22-1971. Heads were installed from factory for the 1972 Chevy vehicles. Great condition and ready to bolt on your Small Block Chevy. 300.00 dollars buys them. Very nice set of heads for your street car. Hardened seats for use of unleaded fuel. No porting done, factory untouched heads. Heads were rebuilt by Varney's Machine Shop Muskegon Mich. Why buy new when you can get these for a fraction of the cost of new heads. These 1.94 intake valve heads make for a nice street engine and power band. I will ship heads to your location for additional charge. Send me a message with your email address and i will send you pictures.
