Of the '70 Pontiac 455 big valve engines, only the stick coded engines had the S grind (068) cam. Have torn down too many originals, a WA, 2 YA's, a YC, & over a half dozen XF's with original cams. Have not removed the original cam from my '69 428 HO GP's XG engine, but am betting since its an auto code, it will also have the P cam.
