will they support 500+ supercharged rwhp and 10 second timeslips? anybody running these heads with a trick flow track heat intake?

for the same price just get TWs or afr185s... i bought the ys because i wanted alum, and i was on a severe budget.

For 500whp, I'd look at AFR 165s, or if you want to stick with Ford, the Z304 heads.
