You had me worried over nothing. I can wait a week.
One interesting thing: I noticed that the aluminum bar that I use to hold the COPs down gets hot (probably from the valve cover, I'm using risers made from copper tubing), but I was thinking that with a thermally conductive barrier material you could probably use an aluminum bar as a heat sink to provide further protection against heat, at least for those of us running high rpm and wasted spark (though the coils haven't died yet from 7000+ rpm usage and 5ms dwell, so I'm guessing this is probably not that drastic an overclock). You'd have to make the risers out of a thermal insulating material to isolate the bar from the valve cover, but it might help (though how much it would help under the hot hood, I don't know.
Oh yeah, pic from other thread:

I'll mention that with Sav and see what he thinks about thermally insulated systems. I'm not sure that it would make that much difference, but it would have to help.
I also sent out invoices for international shipping to those of you who live outside the United States. Its 7 dollars flat rate for international those should be in your mailboxes.

I agree it wouldn't make much difference if the dwell is low, even in a wasted spark config.
The idea would be to have the retaining bar be thermally connected to the COPs so they could draw heat off but thermally isolated from the valve cover to ensure that it stays as cool as possible to maximize COP cooling.

You have $$.
I just installed my COPs over the weekend and Savington was nice enough to inform me of this necessary modification. The car is running great, and the COPs will now be able to last longer.

At this point its more the going price, then a group buy. We're not making alot, but I have plenty of stock to sell, just order on the website, and I'll get you taken care of.
