I ran the car low on oil and believe I burnt out my 1st and 3rd cylinder valves.I also took it to my post craft shop and ran a compression test reveling the 1st and 3rd pistons at 0. Thanks

We removed the spark plugs and and tested the pressure with a gauge while I tried turning the car on if that helps

If you have 0psi compression that would be the valve not rings unless the piston had a chunk missing or wasnt going up and down. Ethier way the head has to come off. Those heads are easy to pull and disassembly.

I'm answering for dmartin321, we did both a wet and dry compression test. It all started when his timing sprocket shattered. We have removed everything and replaced the 2 sprockets, tensioner and chain with a new one. I'm afraid when is shattered it damaged the valves. Again 0psi on cylinders 1 and 3. Thanks
