[SuperNovaSS]

This is a pair of matched 3919840 Heads. They have rectangular intake ports and closed combustion chambers. These were used on 67-69 L71s, L78s, and L72s. The heads are dated K 1 7 and K 2 7 which is November 1st and 2nd, 1967.

These heads are very nice with no porting. They were tumbled and magged years ago. New valves were bought for them and the heads were put on the shelf and never used again. Just to be safe, they were recently remagged and given a clean bill of health.
