Can you tell me if these comp test numbers are bad I know that they are. I just want to get you guy's opinions
cyl/psi
1/95
2/120
3/135
4/150
5/150
6/100
7/150
8/ Didn't do it because it's too hard to get to and screw in with the hose in the way. I figured the results were bad enough anyway in the other cylinders. I wish I had a air comp to to a leak down.
Looks like I need to take the heads off?
*History* My car would turn over but wouldn't crank. I checked the timing and it was off one tooth. (TR230/224 no advance ground in) I corrected it and the car still wouldn't fire.
Maybe being off a tooth caused the valves to hit?
Any comments?

Pulled the pass head tonight. There are no marks on the pistons.
I decided to turn off the garage light and shine a flashlight under the combustion chambers and I see rings of light around the exhaust valves in cyl 2 and 6. The same cyls that gave me 120psi and 100psi on the comp test.
I bet the valves on 1 and 3 look ugly!
I think I found my non starting issues. And the reason why the charge kept backfiring into the intake when I tried to turn it over.
