Should I pull the engine and do a rebuild?

My 90 GST is broke again. I would like your opinion if its time to pull it out and start again.

Last summer it blow its head gasket. At that time I had the head in the shop for resurfacing and seals. I had them replace the minimal amount to get me back on the road. I ended up putting two new valves in. I did the timing belt and water pump, along with any other little things I could think of.

Now, I think I may have blown the head again or worse. I'm not sure what the hell is going on with it this time, but I do know I have this urge to pull the damn thing and replace or rebuild it all. If the problems with the block, will that cause me to blow the head gasket again?

I posted a threads, and you guys have tried you best to help me. I'm not the most experienced mechanic and diagnosing sucks. I feel like I'm chasing my tail here, fixing and braking, fixing and so on.

This time around I ordered a new timing belt (last summers has a groove from oil pan bolt )and belt pulleys(not done last time), New plug wires, new oil pump(I didn't know to do this with t-belt ), and a timing light.

So what do ya think. Time to get my ass back to the garage and throw another head gasket in, or start peeling hoses and wires?

Have you done a compression test if so what were the results?

I cant start it so the numbers are cold. They range from 35 - 55 psi. Thats the bad part, because shouldn't one be low if its the head gasket not all?

when you put the last head gasket on, what pattern did you use to tighten the head bolts? if you tighten from outside in, it could misplace the gasket. also, did you use any kind of sealant?
