Stock Vortec valve springs are weak.
Stock vortec valve lift is limited to .470"

Crane has several low lift HYD Roller cams that will fit the Vortec motor with a valve spring upgrade for better power above 4500 RPM.

This one is better than stock and can use all your stock parts. ... il&p=24206

Lingenfelter 74216. The one shown below is with 1.6 rocker. With a 1.5 your lift would almost max your springs. Do a google search for LPE 74216. A lot of people love it. ... fA9B6yuq1g
