650 head on 701

[whennotsailing]

Can I do it? Have an old one around with a nice powder coat on it... I know diameter a little different, do I get a small compression boost to boot?

I wouldnt do it. The squish band of a 650 wont line up with the top of the 701 piston so it could cause detination at the edge of the piston. It may even give u less power.
