RRR,
Post #9. Loose can damage the valve train, so if lash is unknown, better to set tight. It will NOT cause damage to set to 012-014. Setting too tight, like 6 or 8, might cause burned exh valves because the valves are not seated long enough to transfer heat to the valve seats. Really only likely on very long duration cams.
.022 and .024 is not too loose. It's right about the middle. I disagree. I think tight lashing can cause damage if lobes are not designed for it. I'd consider .028-.032 loose.
