If you adjusted the valves again before you have any
oil pressure to work the lifters they are to tight. Back them all off and start over. If you adjust them to were the pushrods will just stop turning with the cam lobes on the bottom you should be fine. Do not second guess after you turn it over by hand. The lifters will go down with out
oil pressure to hold them up.
You need to back them off so the lifters will return to the top of the travel. You want to adjust them so they just sit off the retainer. A bit loose is better than to tight at start up with a new cam. You can always go back and adjust them a bit tighter if you get a noisy one.
