Twisted wedge heads is the way to go if you got bucks... There are a couple of GT-40 heads out there. The regular cast iron heads come off a 302 and can be made to fit a 351W if you drill out the headbolts to from exisitng 7/16 to 1/2 inch. Hot Rod Magazine had an article bout 5-6 months ago. I think the other numbers mean cast iron or aluminum I have been told the "P" series is the best and any 302 or any small/large blocks from Mexice are good becasue there is extra nickle content in their
ores down there
Good Luck

Steve
