that description is messed;
and I seem unable to use the link.
RAI = 744
RAII = 041

The 067 was the most common used grind for Pontiac, and iirc it was used up to 1976 in most of the (non-RA) 4bbl “performance” (or ‘bread and butter’) engines;
iirc 1967-1972(?) L78 used it, and 1970-1976 L75 used it.

The 068 is a pretty mild cam.
