I decided to go with AFR 165cc heads. The CNC porting was attractive
and the reported high intake velocity was what I wanted for my daily driver.
I saved a few bucks by buying them during a group purchase.
 

Notice how much wider the AFR exhaust port is than the stock heads.

This required porting on the turbo manifolds.
I made a template from a CNC laser (I program them for a living).
They were blended in to about an inch back.
