"302" head question

what would possibly dictate the need RACE aluminum rockers on a 302 head? what kinda lifts on a 302 head would cause interferance? .600"?


last time I checked a valvespring wasn't a tuning fork. if your valve is moving around you have bigger problems then valvespring design.



What the hell?
It's harmonics
Man I seriously doubt you've done shizzle

Run what ever spring you need for the cam and for the specific app street or drag, weather it's regular or beehive.

U never run 1.80+ installed height on a sb mopar huh?
How about some aluminum roller tip's on top of that?
Toss in .550 -.620 lift.....
Beehives sound pretty good now.

food 4 thought.

On the rocker bit, Who knows what, it's called 'information', do what u will with it...
