Any suggestions to resolve noisy lifter issue

I am running a Melling RA4 cam with Comp Cams lifter thru Butler 852B which have been discontinued. The valve train is pretty noisy with these lifters and I was wondering is anyone had some ideas. I have lashed at zero plus a half turn and now 3/4 turn and they clack like heck. Oil pressure is at 65lb. Could it be these are made for high load valve springs and my running stock is causing this? Any thoughts welcome.
