oh, those 236- heads do stuff like THIS! ( see pic below) There are a couple of peanut port (PP) build threads here that may interest you.
I'm not familiar with the 702, although I know they're small chamber and would give you more compression. The 236-s are spot on the right head for a 1200-5000 rpm motor, and even more.
more compression ( which = TQ) , or more port TQ with the 236 PP heads? Personally, I may leave the 236's on there, but be somewhat picky about my camshaft. You can build compression with valve events.
Are you considering the extra expense of a hyd roller or staying flat tappet?
