The needed lifter will come with any cam and lifter kit, The stock rocker are cheap from the dealer if you dont get them with the heads or you can use chevy rockers which you can get any place a lot cheaper then shaft mount stuff.
Hes going to need to measure to make sure he gets the right pushrods if he mills heads and block any ways.
He will also need magnum head bolts. $30 from the dealer.
It doesnt really cost any extra to go with the Magnums.
