Cylinder Head Secondary Shaft Bore Plugs - ZR-1 Net Registry Forums

Jagdpanzer · 07-18-2010

For the 402 LT5 stroker project I will be ditching the secondaries.
Turned out these aluminum pieces on the lathe to plug the shaft bores remaining in the cylinder heads. The plugs are slightly oversized, sealed with a dab of Loctite 462 and driven in with a hammer. Protruding part will be taken care of during porting. For the upper blind hole I drilled a small hole through the plug in order to vent the air trapped behind it as it was driven in.
