Hello. Sorry my bad english.I`m from Finland I have -68 350 Skylark and new lifters (Sealed Power HT-969) with oil hole at bottom. It`s necessary and ok just use similiar, but hollow push rods? For example Enginetech EPR317
Technically, those are wrong lifters for 68. 68 rockers have a 3/8 ball socket, ht-969 lifters have a 5/16 ball socket. You really should use the ta performance hybrid pushrods. You can probably use the ones you listed. I can’t say you wont have issues
