Anyone running these cams? Trying to figure out what vacuum should be at idle. Should be less than stock.

It depends on more factors than just the cams…

Engine health, idle RPM, temperature delta and elevation to name a few more. No one is going to be able to give you an estimate that is remotely accurate. If you’re worried about a vacuum leak, do a smoke test, if you’re worried about engine health, do a compression and leak down. Once you’re satisfied all the mechanical aspects of the engine is taken care of then you can get a baseline for your engine.
