Fresh rebuild or an engine that's been in storage, or ?
Priming the oil system, using the correct lubricant additives, coating the cam lobes/lifters w/break in grease, etc. are all important. If the cam is new the engine cannot idle for about the first 30 minutes, engine speed varying and above 2000 rpm.
A page w/info on prepping/starting a rebuilt engine can be seen here
