car wont start

ok this is where im at...first I installed a old fuel pressure gauge and was able to set the fuel pressure to 5psi, then I pulled the plugs here are the results...1( 90 ps1 ) 2 (90 psi) 3 ( 100 psi) 4 (88psi) 5 (90 psi) 6 ( 92psi ) 7 (90 psi ) 8 ( 94psi) these were taken when the engine was cold

Variations of cylinder pressures are in a decent range. Certainly no dead cylinders, but no way to know of the wear is excessive. It certainly ought to fire and run with those compression numbers. The actual numbers are low but we don't know what cam is in it. OP, can you tell us anything about the cam? I'd put a few drops of motor oil in each cylinder, just in case the oil got washed down with excess fuel, forget about that for now, and focus on other things.

So a bad fuel pressure gauge, you think? Sounds like it. With this, the observation of the mist back out of the carb needs re-examining. The idea of an intake valve sticking is disproved by the compression numbers being so consistent across the cylinders. Honestly it sounds like the cam or ignition are way out off; that could cause the mist back out of the carb.

the engine was built years ago, and stored with lotsa marvel mystery oil. put it in the car last year as I was doing work on it, I put break in oil and ran it, it was getting low vacumn 10" I noticed a anti freeze leak coming out the front corner of the left cylinder ( front). the person who built the engine didn't put sealant on the head bolts. I pulled the heads, installed new head gaskets and new arp bolts. while I had the heads off I noticed all the valves on the heads carbon on them except the valves on number 1 cylinder they were spotless. I put everything together and torqued to specs, I then started the car to these problems

So, it is correct to think you pulled the distributor when you R&R'd the heads? In that case, the mist out of the carb and the distributor R&R make me think the ignition timing is now way off due to the distributor not being put in right.
