I have a 396 stroker in my 95 Z28, with AFR 210cc heads Competition porting. Would you send these heads off to GTP for additional porting? How much gains would be likely? Thanks for the info.

 

If they were mine I would send them to Phil at advanced induction.Probably cheaper and better work.

 

I thought you were selling your car why put more money in it if you are going to sell it... but to answer your ? Do a search on GTP and read alot of post about them and then ask that ? again to yourself... L8R Sean

 

Iam still selling my car, these intentions about my heads are for the future. Just thinking what I might do if I keep the car.

 

Take your AFR's here...you won't be disappointed.

Simply put...NO! I don't think GTP is worth the money. Like joeSS97 mentioned, Phil at Advanced Induction seems to do good work. Also, people have been pleased with Lloyd Elliot's work.
