Could a hole in the header and too much fuel put a hole in a piston if running high rpms?

Hey guys, I am still trying to diagnosis this, Just scanned and got 2 degrees of knock, but it is just spikes of knock retard then imediatly falls. I think I know what it could be.
I installed hinson motor mounts, I wanted stock height but for some reason they were are lil taller, dont know why, but the intake is right up against the firewall, would this cause false knock, There is absolutly no room between the intake and cowel(fire wall). Thoughts would be great.Suggestions?

This graph shows barley off idle and I am getting knock spike, The engine is not under load, would indicate to me that its false knock, you guys agree, Please help!!!

ok so looking at everyone of my graphs, the knock starts off idle to acceleration. Something is hitting something or rubbing, I think my motor mounts are too high up, Do you guys agree????
