Tru,
Are your lifters hydraulic or solids, and is the noise from just one side or both sides? My solid lifter engine always makes some noise as you can't adjust them to tight. One guy here was going to get all of that noise out of his engine and he did. It ran really quite after about 1 mile as he bent almost every pushrod in it and really messed it up in general. I think he really thightened down the rockers past just touching the top of the push rods though as he is one of those if a little if good a lot is better type.
