Which companies do head porting. I have a set of 317s I wanna get reworked and wondering who you have dealt with or who you would recommend. They are all priced around 1k + or - 200 bucks so I guess it would just be a matter of prefference.

 

They where selling some here in the forum bro 243s CNC for like 1300 obo shipped

 

for that price why not buy new ones? like the stage 1's from TSP for $1200

 

Advanced Inductions does pretty good work

 

Check into the PRC heads offered by Texas Speed. They usually have as good or better flow numbers compared to other ported heads that I have seen and the price is really good on them.

 

If you have something you want ported I'd call them. They have had some great proven results. The port job is 1000... that doesn't include new springs etc.

 

Its hard to beat WCCH.

 

Cool deal. Ive already looked at TEA and Advanced inductions. Gonna go look at TSP and WCCH. Keep em coming.

 

Cant go wrong with AI (Advanced Inductions)

 

Advanced Inductions or TEA would be my choice. Look at all builds on LS1Tech under dyno section. They seem to have best results. I like the fact AI uses stock size valves which are lighter and still manage to produce great flow and even better dyno numbers. Plus Phil seems to provide great technical and customer service.
