I havn't checked for boost leaks yet. Would I do that by making sure all the hoses are on tight, or is there a better way? There are no check engine lights on.
If it is the head gasket, would I find that out by checking the compression pressure?

You could make sure that all your connections are tight. But the proper way to boost leak test is to make a boost leak tester which you hook up and put pressure on your system and then see if its leaking (kind of like putting boost into your engine when its off). If you need one I think there is one laying around here that JET made for his car. PM him and see if he still has it, you could come over and borrow it if you want. I live in Woodbury.
If your plugs are gapped to .030 you should be fine at stock boost levels, the only time you should have to go to .028 is when you are running 15psi and above. You could try it but I don't think you will have much luck fixing your problem. If you plug gapping was the problem it would be missing long before you hit 5k or 6k rpm, it would miss as soon as you hitting full boost which I hope would be long before that.
Check all your IC piping and even check your IC itself. They have been known to get little holes in them and they are hard to diagnose. Other than that you are going to have to pressurize your system and make sure its tight. Thats were I would go next.
If thats not it you likely have a fuel supply problem somewhere.
