Cam&Lifter& valvelash?

I think Derek is right. If you put the lash at zero with a solid lifter, when things warm up and expand, you will either bend pushrods or hold the valves open. Lash exists to allow for the clearance change that occurs when things go from cold to hot.

While on this subject, new to me is hyd. lifter combo, 255/350. With Shubeck hyd. lifters, what procedure is recommended to set valves with respect to preload. Always ran solid lifter B/B before, many thanks for any response, Tony Tosto.

I've been running .006" cold with Shubecks. They tighten up .003/.004 hot so I still have some lash.
