Where's a good place to have some LT1 heads ported in Southern California? I'm looking for a reputable place that has experience with LT1's and would like to hear some of your experiences. What gains did you see? How much did it cost? etc...

These guys build Pro Stock motors, and are very familiar with LT1/LS1 stuff.

 

Another vote for Race Prep.

 

West Coast Racing Cylinder heads in the San Fernando valley....does stuff for some of the nascar and NHRA guys on occasion.
