    63M 1100 Head on a 65U 1200 engine. Would it work?

    Hi I would like to know if the 63M head from a waveraider 1100 would bolt right up on to a 65U Gp1200 cylinder jug/engine. I can't seem to find info on this. I have seen the other way around but not what I'm asking.

    I think you would have issues with the squish as the domes would be set for 81mm pistons and not 84mm. Someone else more knowledgeable would need to confirm this... Maybe the squish band is big enough to allow 84mm piston... Don't know... But food for thought.

    Yeah, I didn't think about that. Good point. I'm not sure either if the squish band is the same or not. Hopefully somebody else that knows chimes in.
