1970 #291 Big Block Square Port Heads
 

I have a nice stock set of complete square port heads casting number 3964291 both dated E-07-0. The heads have no porting or milling and still have the stock 2.19 intake and 1.88 exhaust valves in them. These heads were used on 1970 454-450HP LS6 chevelle's and 1970 396-375HP L78 chevelle's, camaro's and nova's. Would make a great set for a restoration or pro stock set up. $1250 for the set and can ship them if you cannot pick them up and can be reached at 330-770-2517 for any questions.
