Re: 470 Head modification help
Forgot to tell ya I bought new head bolts @ 20.00 a piece,and had a hard time getting them. The head is a 460 Ford head with a stainless steel pipe installed in the front of the water jacket. If ya got the exhaust manifold off check the thickness of the metal in the top of each port hole, they rot out and get very thin. You might want to replace it!
