What is the best way to go about porting heads for a turbocharged car? Do you want to have the ports hogged out for max CFM?

 

I'd say to port them the same way you would port a normal small block head, except that it may be beneficial to leave the exhaust ports slightly narrow to increase exhaust velocity as much as possible to promote a quick spool. Not totally certain though, I don't port my own heads.

 

What kind of heads are they first off?
The main thing you want to do to all turbo heads unless your doing some kind of super lame set up is polish the combustion chamber and valve bottems like I did to my V6 heads on my cardomain site. Mainly so no carbon sticks to the chamber and causes little buring embers called hot spots to light your fuel mixture.
