Hello all

I purchased a car with a GSR set up and was told the head was ported and polished.

plan on doing some more work to the car so I will be pulling the head. Will I be able to tell if it was ported/polished with the eye?

may be a silly question

 

It should be pretty obvious when you see inside intake side runners. So, Yes you will be able to tell by eye.

 

right on. Thanks.

do you know if Ferrea valves have an identification markings on them?
