Trevor, should we assume you have the clattering lifter problem? If so, are you aware of all the other associated suspect contributors to the problem before you go ahead and assume your lifters themselves are the problem? If not, it's a huge subject still with some unknowns and maybe you should start by reading some of the thousands of words written about it here before just throwing parts at it. If you've already been thru all that, my apologies.

Does you engine have the upgraded cam spacer and thrust plate? Have you tried running 1/2 quart over full on oil? What kinds of oil pressures do you get, hot at road speed and hot idle? Again, apologies if you've given us all this before and I just missed it.
