Default PRC 5.3's on 402 LQ4

Has anyone run these on their stroked LQ4's. Ive got these heads on my ls1 (62cc) right now and am thinking about doing a winter build on an LQ4/LQ9. Could I squeeze 500whp out if these heads or would I be better off with some worked 799's or an after market casting?

I have them on my 370 LQ9 with a fairly big cam, LS6 intake, and 4.10 gears. Running 11.5:1 compression as well. 500 rwhp is pretty ambitious, but it's possible
