I think this is a pair of heads Butler had in stock for quite some time, were on Ebay once, and he bought them, had them CNC ported. I may be wrong. but I saw identical heads on ebay a few years ago. yes that would be them I'd assume. pro ports have a raised port, and a solid rocker stud boss down the middle. and the bottom of the intake port face is scalloped back.
