Since picking up the CTS-V I've been trying to research all of the different options that come with trying to modify these motors.
Over the winter I plan on getting new heads and cams. A buddy who knows more than I do, tells me I should find some CNC 243 heads from a big name like Tick or Texas Speed. I've been looking at some of the stuff at Advanced Induction, as the pricing seems a little more cost effective.

Today I noticed a few LS3 complete conversions for sale. While the seller describes this as a good solution, I'm being told that these heads have a history of blowing motors when tracked.

Really all I'm looking to do is add some street able cams and have heads that will maximize their potential. I haven't even begun to look at cam options. From what I can tell there are a few thousand to pick from, and then customer grinds on top of that.
The car will have occasional track/autocross duty and regular street duty. Any suggestion?
