About 8 track days and 2,000 street miles. After mild cam install... everything else stock including exhaust manifolds. Running E32.

#1 in the top left corner

They look fine.

Thanks, I basically think so too. But a little uneven and 110k mile injectors are at 95% in the top end... thinking this could be cause. Also #2 looks the worst with some white crud on the ground strap. #2 older plugs had some center electrode material removed, so thinking potentially some light detonation.

A couple look the tiniest bit lean. Some of the white Ash may be fuel additives burning off in the high temperatures, but this is to be expected with the 8 track days.
