These heads are fresh from local builder. I don't know much about them as they were on an engine I bought for the short block. It has not been run since freshened. Here's what I do know, raised runner with matching Holley strip dom intake, older Jesel shaft system (1.5 ratio) and a set of cast aluminum valve covers. If someone is interested i'll check on chamber size etc. Brodix says they are good for a 355/406 but the guy had them on a 421 and said it made about 600 at the crank with 12.5 to 1 comp and a circle track solid roller. $1500.00 for everything
