I would start by removing the heat wrap on your exhaust manifold.

this is a very good start... you should have little or no KR with what you are running.. heatwrap from what i understand is used to keep the heat away from sensitive items such as the starter, and many times will actually have a detrimental effect by traping heat

Correct...heat wrap = heat transfered to combustion chamber = heat soak = pre-ignition = kr

Wouldn't ceramic coated headers/PEMS have the same effect then? Many swear by them to keep engine bay temps down.

Matt...what octane of fuel are you running and how much stuff is mixed in for the winter by your state?

Ok..I'd hold off on the header wrap for a couple minutes. Put a tank of real gas in there.

Cfoote'* 96 had 87 during the summer and 12 degrees of KR
My 95 SC had 93 and 0 KR.
