Roller lifters A engine

I bought the lifters years ago from mopar performance,they are Crane lifters,and I believe I have no choice but to block the right oil gallery.I donot want to spend more money on newer lifters,and bushing the lifter bores is not in the budget.I thought if someone had the tube kit they could measure the drill size ,of the drill that comes in the kit so I can order one that is the correct size.

Thanks for the replys
