Calling all gen 3 hemi gurus

Seems to be all years 5.7. I thought at first just the MDS intake lifters. I have disassembled an 06(MDS), a 2011(MDS), and a 2013(MDS). All had bad intake lifters, wiping out the camshaft, too. Now I have an 05 2500 in the shop (non-MDS) with 4 lifters on the right bank wiped out. Intake and exhaust. Engine was already a re-man. Was wondering what parts to use gonig back together. Truck probably won't last long enough to wear out another set, but, want to do this right.
