The xs power and LPP headers are one in the same I too had to grind my k-member slightly but the quality and fit is great.

Usual, cam, exhaust ect, Put out like 360 rwhp, we added the stepped headers at the shop and back on the dyno, made like 361, but again like you said, maybe higher HP cars make a difference and just because it didnt do anything on this car doesnt mean another might pick up a few, we had 2 cars from 2 brothers, identical mods, and almost the same mileage, one car made 20 more HP than the other, go figure. clearances on the motor from the factory? pcm?

I just ordered these headers http://xs-power.com/chevrolet-headers-11.htm so I'm hoping they fit well and don't leak, anyone have any other reviews on these headers?
UPDATE: headers and y pipe arrived today and I am very pleased with the fit and finish but I'm going to coat them inside and out with high temp ceramic paint to keep under hood temps down. For the record these are a clone of the Kook's, I'm looking at the pipe layout of the XS Power and they're exactly like the Kook's, this is great.
Anyone know if there's room between the collector and floorpan to install v-band clamps?
