The aluminum head topic comes up at least twice a year but no one is willing to give up the $20K to get the project started. Go to .org and search aluminum head.
With performance from the stock heads like Ryans and other boosted cars. I see no real point in investing the money in something like that. Couple of guys went out and paid $3500+ for the high buck cranks. They turned out as heavy or heavier than the the stock units. One team spent lots of bucks on lighten their cranks and the fastest run they ever made....was with a stock steel crank after they broke the last light one they had....it was also the fastest 60' they ever had. ;)
