the heads fit, the 70ces head runs a neg squish band, they ( the factory) run it fat out of the box. they all fit each other. a 70 ces is just a 70 with jacked exhaust and a cow bell tuna, you can make a copy of a 70ces from a 60hp. Hydrotec is stand up, if they say it works for 7-10hp, it will.

stock 70ces makes 70 hp right about 64-6500 rpm. the crank is the weak link

Cool thanks Fred,
I plan on welding the crank over the winter. I saw photos of a head that had been machined so it has positive squish, not been tested yet but I'm keen to hear how it goes.
