I believe the old Havasu films show them but in a mad pack of engines

Other than the cut they look the same

Yea...looks like the one on the right would be a much higher compression head.

That 135 head has had a bit done on exhaust side. KR and CCC really close, never did mold them to see if exact but to the eye very close.

Power yes I have cut the bridges out but saw very little gain and lived much better with them.

Is that CCC head stock or is it milled?

If cut not very much.

which part of that chamber should be down to 040" or so clearance and which parts should be left to make up the chamber for whatever psi you want?
Does it work if you apply squish to the exhaust side of the piston?

Entire intake from surface around radius to flat on floor along with the angle on exhaust side. The .040 would be minimum amount.

the exhaust side of the piston is never very flat to match the head plus slightly higher in the middle
In most cases the pinch would be inside and not out the outer edge of the piston I would think?
Seems a little work on the head on the exhaust side could be done to get a nice squish on both sides of the piston?

That mutha would haul but.
