333882 was used from 73 to 80 on 350s and 400s If it has the steam holes
drilled in then its for a 400. if not its for a 350. It was also used w/o
steam holes on Z28 350 74-76.
This page shows the location of the steam holes for a 400 head. I was
drilling the holes for my 400 block (picture towards the bottom of the
page):

462624 was used on 350 Corvettes and Camaros from 1971-85, its a high
performance head. It was also used on some 400 truck blocks.
Edelbrock performer cam would work. I would be more worried about what
rear
end ratio you have and tranny type (overdrive, auto, manual?). If you need
torque than get a higher rear end ratio - 3.73 or 4.11
