302 casting on a set of 318 heads

302 heads are better on the 318. They have improved port flow design over stock 318 heads of the 70s. Bolt right on to the LA 318s and intakes, Run great with Factory Mopar valve train.

Here is Brian's Quote on how many rpms it will go and still keep pulling:

"I ran mine to 5000 rpm and it was still pulling great, Ran out of room on the road. My guess it would have made 6000 rpm and still pulled some or floated."
