i remember hearing that you can't tell the difference (in size) between a 326 and a 455, so the difference in cylinder heads must be flow rate, right? now, i've got a 326 i'm going to be stroking to a 372. and i'm thinking about buying a nice new pair of aluminum edelbrock heads. it says "designed for 1965-79 389-455c.i.d. pontiac engines". can i use a pair for my soon-to-be 372?
thanks in advance
