302 casting potential?

If you buy heads and don't check them, you are screwing yourself.
Thats just what you should do at this level.
I have a flow sheet for a set of W2 econo's from the 80's that were ootb stock that only flowed 214cfm @25 or 226@ 28

they are advertised to flow 260 or so @.500 or something, so yeah people get ripped, and most never know it...

but they spend a long time disappointed with the performance or lack of.
