Can someone please help me identify who ported these heads and help identify the springs.

according to the information i got these are GTP ported Stage 2.5 Ported 862 heads with comp cam dual valve spring kit and upgraded valves. 2.02 int. 1.57 ex.

 

Looks like a home hackjob to me. Cnc machine leaves tell tale marks in the port, and I see a lot of inconsistenes in the posts and the shape of the chamber around the perimeter looks funky.

Springs, who knows. It's hard to identify springs by looking at them. Have them tested and compare to new specs.

 

Thanks for the reply..Definitely getting the heads/springs checked out.

FYI GTP does the CNC first then finish them off by hand. Not sure if it will make a difference in appearance but they dont look like a hack job in person.

 

I shouldn't have used "hack job" they are definitely good looking ports, but it looks like they have been totally hand ported.

 

Lol okay you had me worried there. For the price I think I got a good deal considering it already has a bigger valve job done, upgraded valves and crossing fingers the springs are Comp Cam.

 

BTW what's the best way to clean these up to remove some of the carbon build up?

 

anyone else got any idea who couldve ported them?
