There's obviously some kind of design flaw in our car SOMEWHERE that is cuasing it. NO car should have that problem if properly maintained, but my car does it and I keep up on it like mad. If a nice aluminum radiator doesn't help me, I'm swapping the damn heads!! I'll even settle for some iron gt-40's over the stockers.
hey, you're absolutely right its the heads, there is a theory on how efficient the head is translates into how much timing it can run.. as carbon builds up on the valves, increases compression and you have to reduce timing/increase fuel octane..
my new heads (ported edelbrock aluminum) can run 16* timing on a J4J1 program with 87 octane and no pinging yet.. crazy !
