I was going to leave it stock...

I always like to check lifter spin before installing the intake. With hyd cam install the valve train and spin the oil pump with a drill and turn the motor over by hand. You should see oil pressure on the gauge and up to each head. Put a sharpie dot on each lifter. If they spin with turning the motor over by hand and with oil pressure I would be happy. With solids no need for oil pressure, just set the lash and see if they spin. If they spin at hand crank speed they will live unless trash from somewhere else flows in and jams them up later. Sorry for your loss.
