Default RE: Barely starts and then dies in 5 Seconds

I have Figured out how to align the timing marks and get everything back together. I pulled the plugs and did a compression test. Here are the numbers (front left to right, Facing the engine):

100 | 150 | 125 | 150
1 2 34 ( I think thats how they are ordered)

Anyhow if 1 and 3 would both have been 125 Psi. I would feel good enough to drive it. However a 33% drop in pressure from Highest to lowest is too much to be able to explain away with engine wear. Am I correct in the understanding that 1 & 3 travel up and down together? If so, then I would say some valves got smacked around a bit for sure.

Anyone Know where I can get a good used head for a turbo car????

1+3 are really low.
Are you sure you did it correctly? Here's a reference..

I believe it goes 1+4 and 2+3. Something isn't right with your figures bud.

It was late and I did only the dry test and didn't pull the MPI fuse. I Cranked the engine 6 times each and did the test twice for each cylinder. It is about 100 degrees outside now and I was soaked from sweating. It was a real pain in the tailpipe getting the auto tensioner adjusted properly without the special DSM tools and I just wanted 30 minutes of Air conditioning before I went to bed. I plan on doing the wet test sunday afternoon when its going to be 4,000 degrees outside. I have an adaptor I can use to pressurize the cylinders, If its quiet enough outside I should be able to hear where the air is escaping.

Again thanks for the inputs.

Finally found time to do a "wet" test. cylinder pressures went up across the board. 200 | 200 | 180 | 200. I'm going to order some parts and put it back together.
