RC-51 cylinder heads on a VTR?
Anybody ever tried fitting RC-51 cylinder heads to the top end of a Superhawk? Rods and pistons? Crankshaft? How interchangeable are internal parts between the two motors?

Not even close!!!
I've built both. They are entirely different engines.
RC51 has 4 head bolts, VTR has 5.
RC51 has gear-driven cams, VTR has chains.
RC51 gets oil to the main and rod bearings through the end of the crank, VTR oil comes through the left side main bearing.
RC51 stroke and bore are different.
Valve stem seals transmission output seal and shifter seal are interchangeable...
