APE has finish the total rebuilding and upgrading on the famed RC Engineering Sorcerer Top Fuel Motorcycle. One head is an original. The one that fits backwards had to be remanufactured from a good stock core. We thank Byron Hines for undertaking all the modifications of make it fit backwards, after all, he had made the original one.
APE developed our line of high temp racing stainless steel valves for these heads and the RC Triple heads we did last year. The original heads had old discontinued valves and there were no stainless, hard chrome valves suitable for blown nitro available. The Honda 750 community now has access to these very same valves.
The rest of the components used, valve guides, valve springs, titanium retainers are all off the shelf APE items. Check out;
