I heard of some people doing that swap but I dont know actuall numbers I do know they flow better so if its not going to cost you anything to put them on do it but you should have them maxed out just for good measure

The only year that you'll see a big difference is pre 70. THe 69 heads are the best though and only flow 10% less air than a set of edelbrock aluminum heads.

thanks cause they are early 70s/69 heads then they are a good steal then ill have to thank my dads friend hes an old timer and prob ahd no idea! my score!

you will need some bushings cause the
bolt holes are bigger on those heads than what your 302 uses

they're really cheap though.
