What are headers really worth? About 40rwhp it turns out.. Well I posted up here about some disappointing results with my car..
I've now deleted that thread instead of having two on the same subject / car.
I'm sure a lot of people wonder what headers are really worth on a modded car, and since I was dumb enough to do a build-up and save headers for last, I can tell everyone exactly what headers are worth on a normal street / strip car.
My mods are simple, and common for the LS1 world
Stock LS1 block 90 000+ miles
T56
LS6 intake
EPS 226/234, .598/.601 Cam
Hooker headers
Stock 243 heads
Comp Springs
All mods before headers: 347.89HP, after headers: 387.27HP
You can check out the dyno graph below.

You guys really think I can gain 13hp from just a lid? I'd love to hit that magic 400rwhp number but I don't know if it's possible. My engine mods are basically done at this point, there's a 75 shot of nitrous going in ( already have the kit ) and other then that I don't have any plans.

To give you a reference I have a BBK intake, SLP lid &bellow ,TSP 228R cam, kooks 1 3/4 race headers they might be 1 7/8 not sure and a ASP underdrive pulley and got 401.72rwhp and 389tq.
So it can be done and my cam is smaller then yours.

No sarcasm, I just did some searching after reading the post and a lot of guys are making similar power to me with less mods. I think I have the lowest hp with this cam...
