You could have the old lifters fixed if you wanted to work
I've had Delta Camshafts in Tacoma WA(253-572-2474) refinish several sets of old lifters that you can't buy now up scope twocents



The lifter on the right is a solid. It looks like the solid EDM lifters I use. Mine have the snap ring in them like that but are solid and mine have the hole in the side of the lifter for the EDM oiling on the cam lobe and the hole in the top center if you want to use pushrod oiling which I did not as I use the stock bigblock oiling to my rocker shafts. My pusrods are solid and block the top hole. Ron
