E-street vs Promaxx vs 440 Source

PRH said
Not to sound like I’m bragging, but A 500hp 440 built using reworked stock heads is a “no brainer”.

But not all reworked stock heads are equal.
They don’t need to be awesome for that level of performance....... but they do need to at least be “good”.

The heads should be done to a level that’s commensurate with the rest of the build.

It's not bragging at all. It's what I believe and always have. However, I just didn't want to end up in "almost as much money" in the cast as a set of low-end aluminum. I'll be doing more threads in the future on pistons and cams. I've been doing small blocks for years, so I'm trying to pick the brains of the BB guys.
