Servedio says it more than once in this video . If you watch until the end he will say "had I known that (302 head) this was the worst flowing cylinder head for that 318 I wouldn't have chosen it..." or something to that effect. Right here is the proof coming right from Charles Servedios mouth. Hurry up and get some 302 heads I think I saw a set for $750 LOL!
That's got nothing to do with whether the heads are "cutting it" or not, does it? He's still getting some good numbers out of them for what they are.
You know, you've tried to make something out to be what it's not, so just give it a break.
