Default what heads for my 5.3?
probably before I do another Radix, I wanna stick a set of heads on the Yukon. Nothing too fancy, just want to gain some performance, and still pass smog. Any recommendations?

Well AFR's have CARB approval...

Problem with with the 5.3 is the combustion chambers on most aftermarket heads are significantly larger than the stock heads and your CR will drop.

WCCH has some excellent Stage 1 heads for the 5.3!

You could go with the small bore edelbrock heads offered by WCCH. Also CARB approved I believe.
