Ok so my car was boosted. Drove it into driveway and worked on it for about a week to make it back all motor. After I put everything back together had a crank no start issue.

Here is what I checked :

Has spark
Has fuel
Timing is correct, I put a screw driver in cyl #1 and turned the motor counter clockwise until the screw driver didn't go up anymore ( cam gears both pointed up and the 2 - marks lined up.)
Next I check compression: All cylinders have about 110-115 psi. Put some oil into the spark plug holes, tried to start it up again. It almost fired up sounded like the compression got stronger.


You guys think its a headgasket, rings, or valves? When I was turning the motor, I heard like a hissing sound coming out, maybe from the headgasket? Because I have a header and the intake manifold on, pretty sure couldn't hear if it was the valves leaking.


Any thoughts.

And does a boosted car go through rings faster, because you want a boosted car to run a little richer, so the mixture of added fuel makes the rings wear faster? Correct or no.

 

I would start with a leakdown test to determine the cause of your low compression. You basically put each cylinder at TDC and fill with compressed air and see where the air is leaking out from.
And yes to a certain degree, a boosted car will be tuned slightly richer to cover fluctuations in boost pressure and other variables. But a correctly tuned engine will not be so rich that you wash the cylinder walls with gas. Rings are usually taken out by pre-detonation/running lean, caused by a poor tune on the timing or fuel maps.

 

Got to agree with above, a leak down test is needed.
Have you checked valve lash?
Valves may be "tight" it would account for the low compression? 94
