It was one of those Emails from Mancini and a close out run3 years ago.
But if I knew how much core shift was in them I may have passed. 6 out of the 8 ex ports were twisted but cleaned up. 4 of the 8 Intakes too. Very little distance from the manifold bolt hole to the port on two exhaust ports that they may leak. And if I remember, shipping was like $50 each head.
Yes a nice heart shaped chamber. I think 58cc. 2.02" Intake and 1.62" Exhaust.
The Chevy rockers, while not roller fulcrum, are roller tip and 1.6:1 ratio and cost $65 for the set of 16, also 3 years ago.
