I took a look at the numbers that ryan J has in that link you posed for 302's and J heads, and it seems like the J heads have a decent amount more flow...but flow is not everything right? or alteast thats what i read...and man, i wish i knew what you were saying about floor and seat and stuff lol...i think im gonna look for some sort of cylinder head walkthrough video or something, since i need to understand all these terms and such
