302 casting potential?

unless you are going all out with this engine, larger intake valves are a waste of time. the velosity will be killed with the larger valves. exhaust valves should be enlarged but that is it. there are many threads on here reguarding "302" cast heads. look some of them up, then if you still have doubts contact or study some info found on "bj's" site."bjr" is the small block expert on here....

Sorry...but this is not true. As long as the porting/valve job/chamber transition is correct, the larger valve size "allows" more flow and velocity. Period. You can easily find this by probing the port with a pitot tube and see the increase in velocity with FPS using a Superflow Flowcom computer.
That's what I use.
It may be a waste of time if the guy porting does not know how to shape the port correctly and do the valve job/chamber mods.
I've made over 400HP with those heads on a 408 before. Pump gas too.
