^ to the contrary, cheap pushrods are cheap insurance. Sort of like fusible links.
Back in the 1980's a friend had a 455 built by a local shop. As with Dave's motor, they installed 1.7" springs without measuring or checking. They DID use stronger pushrods. When we pulled the valve covers, the strong pushrods had shish-kabobbed the rocker arms. Also wiped out the cam, lifters, and stud damage. If everything is checked, test fit, measured, and adjust properly, THEN high quality pushrods are a good thing :-)

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.
