It would be easier to just list what is stock. Both the intake and exhaust headers are stock. The entire head is stock including the stock cam gears. Beyond that everything else is done. Built bottom end. Built trans, transfer case, all quality bolt ons, runs on e-85, big ass turbo pushing 30psi etc.

Just curious about how far a head rebuild with some big cams and some better headers could take a setup like that. The car is at 500whp as of right now. If I'm going to be spendings thousands of dollars (again) I would like to be approaching 600. Possible?
 
Manifolds not headers. And also you put that much into the car why not do a built head.

Why not just make a DSM profile so others have easy access to your mods?

This is a very vague description and helps members very little to understand your setup or help give accurate info on head work. Again, A DSM profile would solve this issue.

big ass turbo pushing 30psi etc.

Never seen the Specs for a “big ass” turbo? The actual make and model would do wonders here. “Big” tells us nothing useful. The amount of pressure you are creating tells us nothing about how much air you may be flowing (lb/min).

What are your goals (DSM profile)?
 
I know that was weak. My phone was about to die earlier and I was just trying to spit it out. Anyways, I'll go figure out how to make the profile thingy.
 
i would like to say there is no way whoever built that car for you (because it seems to be obvious you didn't) skipped out on the head build. 500hp on a stock head is pretty retarded, if i wanted to reach 500hp the FIRST thing i would build is the head. get us a list of mods and it will be possible to tell what you are missing. what about your fuel? how do you plan on getting fuel for 600hp? can your exhaust setup handle it? are you running speed density? what intake manifold?
 
When I took my "built" head (personally put ~50hours of hand porting/blending/etc into) to my machinist last year and found the cam caps had walked, I threw a spare 6 bolt NT head on.

You can definitely make over 500whp (and then some) without touching a healthy stock head be it 6- or 7- bolt, aside from some setup-appropriate cams and springs.

I'm on a 67mm T4 turbo, E85 and GSC S3s.
 
I have done ported head tests on the dyno and back to back tests with camshafts. The first thing you should spend the money on is a quality set of camshafts that work for your setup. That will gain you the most horsepower. At 400whp I picked up 27hp from JUN 272 cams on a fp 71hta(technically a white for an evo) on a stock port head.
