Oddly enough, there was a shard of stainless steel found in the combustion chamber that was lodged between the #2 piston and the cylinder head. After hours of disassembly and digging, Steve Dinan actually found the culprit to be a tiny piece of welding broken off of my newly purchased (<100 miles) ACTIVE AUTOWERKE headers - a terrible construction flaw. I questioned how the piece essentially swam back upstream into the motor, but Dinan assured me it's surprisingly plausible - someone whose opinion I value beyond measure. He/his shop verified no other failures (not intake, valvetrain, head, block, etc) anywhere else.

As time permits, I'll go into more depth with a writeup.
