RAMM wanted to know about this 451..............

My point is that hardly anyone could get the same results that you guys did with those heads. Might only be a dozen shops in the country who could port those heads and get those results. I couldn't do it and 99% of the guys who post on here couldn't do it. I'm sure your heads were legal and you were competing on a level playing field with the other big boys so I don't have any issue there. I'm just saying that some guy who works on his car in the driveway and owns a few hand tools shouldn't expect to make 700 hp with the RPM heads he buys from Summit. He might make 550 hp with a pump gas 451 but he ain't going to sniff 700.
