Lifted the head
Yeah so I lifted on the car, I have coolant and the whole nine yards in with my oil. so I figure I am going to build the top end some. I plane on doing forged piston arp head studs a better head gasket. I'm not sure if I want to do cams or not. but I know I am going to lower the compression to 8:5-1 and run more boost with a 2.5 and a good tune.

yeah I went back and looked at the log. when I saw the 21lb of boost it went lean I guess the weather had a lot to do with it, it was about 45 degrees out that day.

The stock headgasket is a weak point of our engine. More so are the stock studs. Get a Cometic headgasket and Golden Eagle headstuds and you'll be set. I was running 24psi on my twinscrew with my 2.2L ecotec Cometic headgasket and GE studs without a hitch.
On a side note I don't suggest running 8.5:1 pistons unless you decide to run a turbo. Just use the thicker Cometic 2.2L gasket and it'll lower the compression a bit. Stick with the 9.5:1 comp pistons for the setup you described, and you'll make more power in the end.
