Stopping the knock: Lower compression and ported heads...

Evidently I misunderstood one of your previous replies where I was almost sure you stated you weren't sure where it actually was, as you may've not measured it correctly...moreover, what I was getting at is that if you do retard it a few degrees, it could help out with your high cranking pressure and further reduce your potential for detonation...but I digress...and I'll resume my position purely as an observer...

Yer learnin. lol
