I would wonder about valve lash. It would come from the top, but of course from valve covers.
How was the timing chain?

timing chain was loose a little. I grabbed the front of the crank and pulled up and the chain got more slack in it. so i pulled the motor. and i seen that i flattened my main bearing.

So i got done taking the motor apart. all crank was basically grounded down by the mains, mains are complete shot, and the crank is too. It was like a monster clawing its way out. the whole crank wobbled.
