Getting ready to build a 440. Will be using TrickFlow 240 heads and a Comp flat tappet 23-631-5 which I planned on getting the nitride treatment. I saw AndyF's article about also using the 2901-16 EDM lifters for extra safety. When I looked up those lifters it said they used pushrod oiling? I've assumed the HS rockers for the trickflow head were still oiled via the shaft? Is there something i'm missing if I do wish to run these EDM lifters? Thanks!
