No substitute for a mechanical problem in the head.

Get it to a good shop.

I'd be hesitant on running it just on 5 anyway. When it does finally kick over, are you hearing any pronounced ticking? If you don't feel comfortable with pulling the valve cover and checking it all, nobody will blame you for taking it to a shop.

See if anyone else here has any good insight, and if you do take it to a shop, definitely post up what kind of a diagnosis they had for you and what repair/parts they plan on doing.

Best of luck, keep us updated!

Unluckily that doesn't explain why the gas continues to roll into it and why it smokes on start up.
I've checked all the easy fixes, plugs, wires, distributor cap. If it is my exhaust valve does any one have an idea on a way to try and fix it without yanking my valve cover off? If that's my only way I'm taking ti to a mechanic but you cant blame me for trying to find a cheaper way.
Dude, If you don't know the status/condition of the valve then don't run/drive it. If it drops/bends and jams the piston then you'll be dealing with more than just cylinder head work!

This is true, a simple valve job can turn into a complete engine replacement. Call around to some different shops some have their own tow trucks and may wave the towing fee if you have it fixed by them.
