...now that Cosworth are making RV8 blocks they could be persuaded to sort the heads out, there must be a lot of people out there who would buy sorted hi-flow heads that don't crack or leak
I think some are porous I heard that the Wildcat heads suffered from that. Not sure about Real Steel their website says exhaust ports raised a "little." I think if they had a new casting they would be making more of an effort to market them.
