ATK 5.9 Magnum crate motor horse power

So I just confirmed with ATK: they DO NOT use the EQ (Engine Quest) heads on their iron head 360 crate motors! Stock Magnum heads. Very disappointing. Those stock Magnum heads are extremely crack prone. Why you would use those to save a couple bucks is beyond me. I asked them to consider using the EQ's and charging a bit more. We'll see if I get any response.

Given that, I'd have to scratch ATK from the list. So, my crate engine short list is even shorter now:

No #1 - For sure the BluePrint Engines 408 (BPC4085CTC): 465hp / 494 tq / Alum head / roller cam / $7,300 complete (without damper and water pump) or $7,800 (w/ damper, water pump, air cleaner, plug wires). This is top shelf in my mind, but a little pricey.

No #2 - Same as above but iron heads and flat tappet (BPC4082CTC) : 375hp / 460tq. Saves about $1,300. I assume they use the EQ heads, but need confirmation from BluePrint. If they are stock Magnum heads, then this would have to get scratched from the list too.

No #3 - PIE (Performance Injection Equipment) 360 : 450hp / 465tq / EQ modified iron heads / roller cam / $6,350 complete incl. damper and water pump (but minus carb). CONFIRMED they use the EQ heads, then they modify them from there with mild porting, manganese valve guides and 2.02 intake valves. They do make this as a 408 for $650 more, but then you're getting really close to the BluePrint.

After much research, this is my short list. If anyone knows of a good low-cost EQ-based iron head roller 360, I'd be all ears to add it to the list, but I haven't found it. Thanks all for the good discussion and help.
