Then how would you keep the rods from hitting the camshaft ? There's not a lot of room there.
Plus the head would need some major work to flow that much air !
As far as the rods hitting the camshaft, that wouldn't be a problem with an offset grind. The rod journals can't get any farther away from center at the outside, but the center of the journals gets moved out by making the journals smaller. The rods he's planning on using of course, would need to have smaller journals on the big end to fit the new smaller journals.
I'll let Jerry address your head comment.
