Here's the question you are trying so hard to avoid answering again:

Can a 302 head make the power to push a 3400 brick down the 1/4 in the 11's?
Nobody is using a 302 head to make power. A blueprinted engine, not to mention the rest of the meticulously assembled package is overcoming that head in order to run this hypothetical 3400 lb pig into the 11’s in the 1/4. Because that is the real focus. “Everything else” Not that someone does it because they run that head.
The cars ability to run the times you state and attributing it to the heads is backwards IMO, it will be due to attention to everything else, in spite of the heads. Nobody is running into the 11’s because of the heads, correctly stated it’s that they’d run much better with something else.
