Set of fresh 391 square port heads. Both dated D-11-7. Heads have been completely rebuilt with new stainless valves, 2.19, 1.72, comp 924-16 springs, keepers and 10 degree locks. Guides are nice and have Teflon seals. Heads were magged, bead blasted,hot tanked and cut for straightness but still plenty left on deck surface. No heilicoils and all threads have been chased with a tap. Only mods look to be front of the heads had plugs shaved and some very minor intake gasket matching, see pics. Not ported on either intake or exhaust. Super nice set of rare date heads. Thank you for looking.
