Shoestring, just to confirm, no combustion chamber mods aside from shaving the head? And on the ignition tuning, is it less aggressive than stock at any point or would you be able to run stock ignition timing if you wanted? Iím trying to help a friend get his car faster and heís worried about detonation with 2mm off a 405 head on pump gas.

Youíve run it before? What was the rest of the setup and what gas did you run?
