TEA Stage 3 Heads
The LS6 heads with a flat top in a 408 with a stock gasket will put your around 11.7:1 compression. Some people dont like going that high for some crazy reason.
You might beable to save 700 bucks or so and use the LQ9 heads.
Mill them to 68cc's and run a .040 head gasket.
This gives you 11.6:1 compression and saves you a good amount of money on head cores.
As far as the LS6/AFR TEA ported heads.
I would do the AFR's just because they are a better casting, and for the small price difference why not?
I would do it just so I could say I have AFR ported TEA's.
I have a similar combo as you but am cheep and went with the LQ9's and thinner head gaskets.
I'm going to be putting this together myself, because I'm insane and I want my wife to hate my guts.

Give me a call and we can discuss your option or PM me your number and I will call you!

Thats great.
Glad I am not married, or my wife would have whooped my *** many times by now.
I am south of you and I am almost the exact same setup like I said before.
With 93 octane and the quality tuners we have we should be fine. Brent talked me into the LQ9 heads about a month ago. Haven't recieved them yet but hopefully soon.
Good luck man.
