I just did the head seal job on my '88 - both Bentley and Herb (from the archives) recommended re-adjusting the valves after a 'head job'. I didn't! What I *did* do was keep the valve train with its associated head & keep the pushrods in order. The trick with the rods is mount the rockers hand-tight onto the head with the rods installed. Jiggle each of the rods until it falls into the cup on the lifter. It's unmistakeable when it does! Then push the rocker down onto it to hold it in place. Tighten down the rockers carefully, making sure none of them pop out again (they'll try!). Herb suggested applying goop to the pushrod tube seals. I didn't. So far so good ...
