Got the valve covers off. The valves are adjustable and there are nuts with the hex key locks so I should be in good shape. Looks like the concensus is 1/2 to 1 turn once the lifter starts to compress. Thanks.

Can anybody tell me if the harmonic balancer bolt to the crank is right hand or left hand thread? It doesn't want to budge and I want to be sure before I start thrashing it.
