Timing belt is loose and frayed

I cranked the motor over by hand about 5 complete revs and no interference or clicking noted.

A leak down test will answer that question.

A red neck way to do it is make sure the cylinder is at TDC and on the compression stroke and find a way to put an air hose where the spark plug should be. Blow compressed air in and you will hear it whistling out the intake manifold or the exhaust if the valves are bent. Turn 360 to confirm you are on compression stroke.

I picked up a sweet leak down tester kit at NAPA yesterday so I will know this afternoon what the verdict is.

Any thought on rebuilding the head if needed or purchasing a rebuilt one?
