Unless there is something seriously wrong with those heads, you're golden. You could still benifit by opening up the exhaust ports on those heads, if you are so inclined. You keep messing around, though, and you might accidententally wind up with a badass motor, instead of a little over stock. That all depends on your perspective of performance, though. One man's neck breaker is another's grocery fetcher.

Hey Ford347. And to think it all started when you bought a carb and intake! NOBODY can change just one thing. I sure can't! Oh well . . . . . so much for the "mild upgrade." Have fun with it!!

302's use smaller head bolts than 351w's, the step washers help center the bolts on the heads. Studs are usually better than bolts, because of the way they torque the heads down without twisting. The 2 downsides are that they make it hard to impossible to remove the heads without removing the engine in most engine bays and they cost a lot more. I am not sure , but I would think you would want the washers with the studs as well. I don't think they are a have to have option, but highly reccommended.
