| its just like an ac head with the coooling fins milled off and a water jacket arround it but they are better and are a once piece unit (cyl and water jacket all in one) hope that helps iam prity sure u can bolt a wc head on to an ac motor as long as there same brank like polini ac with a wc head that sort of thing then all you would need is the radiator and pump i think the only real dif in the cases is that one has the pump mounted and the other has none so you would have to mount the pump to the motor some how.
and about the fiberglass rc boat is it notro or has it got a petrol motor in it?
