Mined just started making the same noise, no exhaust leak, fixed 3 bent push rods-its still there. Consensus was it maybe valve damage

Sounds like exhaust leak or valvetrain IMHO, bottom end noises are usually "faster" sounding as the cam turns at half the speed of the crank.

blown head gasket?
swapping compression between 2 cylinders will sound just like a exhaust leak or piston slap

Sounds like a Header gasket leak, possibly Collector gasket as well.

Mike, I will be around this weekend after I get my car tuned. If you wanted to stop by I can look at it. Remember when you through a plug?

You still have my number right?
