The only reason to bush the lifter bores is to keep the lifter oil band covered when you run a high lift camshaft.
I don't know what that lift is.... but if you are running a street cam you may not need to do it.
I know all about budget constraints.... I'm retired but working 60 hours per week to fund my racing and to try to maintain a somewhat normal lifestyle. (Believe me I'm not a spendthrift... I live in an old dump that takes $$$ to maintain!).
You can find good, used lifters. You can tube the block yourself. If you are on FB Jody Cash has a page called " Mopar mafia" and he had a couple videos on the procedure.
