Does anyone know where I can find the correct length for the exhaust valve on a 71 455 V-8.. It is not the HO model, and from what I understand it should be 4.87 inches long, versus the 4.98 inches long... Any help would be fantastic!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
