In the last installment we put the valvetrain together, and if you remember, we had issues with the pushrods rubbing the heads. We fixed this with Isky's adjustable guide plates. But we ran out of space and didn't show you that while we got the pushrods where we thought we wanted them, we totally screwed up the rocker locations. As you can see here, the rockers' roller tips aren't centered on the top of the valve stems. This is an engine failure just waiting to happen.
