Impressive numbers for sure, thumbs up!! I wonder what additional cfm, hp and ft/lbs could be extracted with simple tapered guide bosses and opening the pinch some. I've got those heads and used the standard 1.92 intakes but cleaned up the bowls (didn't need much) tapered and contoured the bosses down into the port (in/ex), gasket matched the intake and ever so slightly blended the pinch. Left exhaust ports alone. You say only bowl work, no exhaust port work at all. Damn, The exhaust #'s are excellent too.
