I got the car fixed just in time for the event. Compression #s are back to 100%. Installed the #9 Iridium plugs as recommended by Kyle and Greg. I ran the car hard all weekend at the PINKS event, while closely watching the A/F ratio (11.6-12.2/1 on C-16). All 6 plugs were a healthy brown color at the end of the weekend. Say what you want, these are the facts. One reason the heat probably dissipated more upward towards the valves, as opposed to the pistons is because my pistons have a ceramic coating added and this coating was listed on my mods list that I emailed you way in advance of the tune. This is a firm belief of what happened by not only my self, but some very knowlegeable folks.
