These American made tappet blocks are machined from 7075-T651 billet aluminum and have a chrome plated finish. They feature corrected pushrod cover angles for aftermarket Evolution Big Bore cases, that have the cam case areas moved out up to 1/4"-3/8".
Note: On large cubic engines it is important to have the free flowing PCV system. We recommend to use the "Through the Head" and early style crankcase system in conjunction for optimum results.
