How much power are you putting down?
I would go with the long tubes since you are pushing 500rwhp.
Assuming that you were talking to me...
Built block, stage 2 heads, oversized valves, beehive springs, custom cams, ported blower, ported upper, chip, 2.80 upper, 8# lower, monster box 2 cat h-pipe... thats it~!

i wonder if your oversized valves allow you to run more boost than normal valves. isnt it kinda funny how we write our list of mods and then at the end we say " thats all" like it isnt much, but at the beginning of the list it says "built long block".
Don't get me wrong, a set of headers will make effiecency improve greatly and reduce the amount of heat being put out. But they can handle it, just they are greatly in need of being removed with anything above 500 rwhp IMHO. I just wanted to see 20#'s on stock exhaust and see what kind of power it could put out. And with the exception of the 2 cats I think I proved it can be done. But once again, good power gains are to be found there over the stock parts, they just are not required to make decent numbers IMHO.
