I would normally agree but have to point out that with even a mininal amount of lifter preload (.001) they would be tight enough not to rattle BUT I'd still be sacrificing some lift (up .040 of lobe lift) and duration. One site I found suggests a rule of thumb that .004 inches of loat lift equals 2-degrees of duration.

Using this information my XE274H cam (advertised at .488 and 230 degrees @.050 INT and .491 and 236 EXH with 1.5 rockers at the valves) could effectively be acting like a much smaller cam (.427 and 210 degrees @.050 INT and .430 and 216 EXH).

The graph that comes up when I use this info on their CamQuest software come up with numbers that mirror the graph I got with the dyno run.
