It wasn't as nice as I 'd hoped, but I am going to drive it for a while since the AC works.

Head bolts are not re-usable, right?

You had said the p-pump stuff is worth 12-1800, what would change the amount so drastically?

They are reusable as long as they aren't stretched too far. The Cummins head gasket kits come with a stretch gauge. The price varies on what injection pump you have. You probably have a 160 on that 94 and they aren't as desirable. They are finicky and don't fuel as well as a 180 or 215. Plus they have a different cam in them that makes them move less fuel. Still an ok pump but not a big dollar pump. A 180 will bring the most and 215s are right behind them. Mileage and condition of the pump are a part of the price too.

The engine has 246k miles on it. How do I check to see what pump it is and what kind of price should I ask, if it is a 160, for it when I go to sell it?

Now that I have put a few hundred miles on it, I think that when I have it in the Suburban I actually may want more power out of it, So far I have only gotten about 15 lbs of boost going up a steep hill full throttle. Is that the maximum boost I should expect, or am I just not going to get more because I am not loaded enough?
It also smokes a little once it is "hot" at idle. What could that mean? it is a white smoke.

The white smoke could be haze from worn injectors. There is an ID tag on the injection pump, usually on the governor housing or on the side of the pump which could be behind the throttle bracket some times. The numbers on there are where the model numbers can be broken down from.

What turbo does it have on it? Plug the waste gate line and make sure the waste gate isn't stuck open. You can get at least 10lbs more out of that turbo I'll bet with some tweaking.

Just plug the port on the can for the waste gate and close off the boost(or vacuum) line from the engine?
