definitely not an exhaust leak. lol
don't think a valve is bent. They are all even with the rockers off. I'm thinking a collapsed lifter is the only other thing it could be ?

You might be able to see the tops of the lifters, with a small light in the hole... A bore scope would be nice. See if one of the plungers is sunk, below the retaining clip...
If all that looks good, compression test it.

Great info here. If you can do the above mentioned would be the next thing. Crazy opinion I had a friends clutch come apart and it sounded like a bad lifter, bad bottom end and took it all apart and found the clutch came apart and was making noise. He had a textralia clutch 0Z700

It could be as simple as a header gasket blown out or even a spark plug loosening. With an over rev before I'd be thinking the header gasket.It had alot of P/V clearance when we checked it.
A blown lifter can be found easilly by rotating the motor and checking the rocker play.

Thanks for the input everybody. I really appreciate it !
I'll look at the car again this weekend and hopefully get to the bottom of it. If all else fails I will haul the car down to you Don.

I limped the car home and parked it. Today I drained the oil to look for any metal shavings or metal pieces. I ran the oil through a paint paper filter and it was as clean as can be.
When I have blown things like bearings, once it spins, your generally already have shavings and glint in the oil. Even doing a fresh change will show immediate contamination upon inspection.
