im teling you there is one on corral and he had to cut metal off the heads in several places. the head itself is not the same as a pi. the ports are, but the head is different. it will fit but metal has to come off. some off the blower and some off the heads.
I may possibly have a blown head gasket, if I do. I will be saving up for these heads......Cushman Motorsports (CMS) have a TF head and cam package that I am just dying to get......
