Merrick....................Nothing has been said yet, but the head has been O ringed? Right!

The 400 HP thing is a shoein. That's really not much power in todays trucks. It will last as long as a stocker, you know that. I know my truck is a 96, but with 325K on the meter I still tow 15K all over the place. I'm at 306 on the dyno and have been there for 4 years. I took out the 370's, I was at 406, cause of to much smoke on the fiver.
Still, 400 is easy and will last from now on.

We shave the pistons .050 for the race engines and make 750 HP. Still they last.

Good luck.

Well,, the head was o-ringed, but because of the "lack of ability" here locally, and my need to get the head straight again, it is no longer o-ring'd, but still has the head studs.

What boost should I be good to? I'm running 40 exactly, with only the MAD ECM, and the Superchip tuner somehow squeezed in there. I do have A-1 Head studs (12mm) trqd to 125lbs.

The truck feels real nice, EGT's peak pretty high (1400-1600) but cool right back down to 1200-1300 once the turbo's light.

I would say you will be good to 50 lbs of boost with the 12mm bolts at 125 lbs. Maybe ever a little more. Thats a good clamp on the gasket, If you know the head is flat, and the sequense was correct on the studs, you will be in good shape. I would feel a lot better if the head was O ringed.
