350 V8 - Cheap Street Chevelle
We cleaned up and reused the World Products S/R Torquer cylinder heads that were installed in an earlier segment (Part III) of the Cheap Street Chevelle buildup. Once the heads are clean, paint them with a quality engine paint like VHT's. The S/R heads are a cost-effective (actually cheaper) alternative to rebuilding a stock set of heads. Plus, the heads flow better than stock units, have hardened exhaust seats and feature 2.02/1.60-inch valves. Once the heads are torqued to spec (65 lb-ft in our case), install and adjust the rocker arm/pushrod combo. With the lifter on the cam lobe's base circle (piston at TDC firing), twist the pushrod with your fingers as you tighten the rocker arm nut. As you start to feel drag on the pushrod, you've reached zero lash. At zero lash, tighten the rocker arm nut approximately three quarters of a turn more. View Related Article
