Have you talked to any machine shops in the area? They may have some advice as well.

here is another way to check the valves. start the engine and let it idle. if you have duals, go to the exhaust end on the #1 cylinder side. place a piece of newpaper over the end of it. let it flap as the pulses come out of the pipe. if it sucks in on a pulse, you have a bad exhaust valve.

I got a xpipe will that still work?

 

[Doober]

You may have to press your hand against one pipe in that case to force all the gases out one side (don't do this after it's warmed up of course :lol, but otherwise it should work.

if it was a valve wouldnt it backfire or pop?

Take the compression tester hose, hook it up to the air compressor, turn the motor until both valves are closed (look at the rockers), put air pressure on the cyclinder, and listen for where the air is leaking out (use a piece of vacuum hose held to your ear and around the valve springs if you have to). If you have headers you'll probably hear it by listening to the tube on that exhaust valve.

If there is no air up top, it's probably leaking down bottom and you might hear it from the oil pan.

If oil doesn't help, then either the rings are completely destroyed or it isn't the rings.
