If you're boring the lifter bores, why would you not put bushings in??

I don't know why, kinda why I'm asking. Why doesn't the factory or any other block manufacturer put bushings in when they bore ?

Why don't they ??

Added cost to manufacture!
Stockers didn't need them in their previous life in passenger cars..
Aftermarket, the need for them depends on your use, Would you need them, if you were running a Hyd. Cam ???

Why would you need a bushing? I may need them and don't know it yet but never had any. They may be easier on lifters?  study

A race engine puts a lot of loads on parts that you'd never see on a production model.
Do you need bushings,,,,,, probably not.
Do you need .904 lifters,,,,,, probably not.
If you do need one, the other should follow. IMHO, I mean if you're already doing the work to make the holes bigger.

I would rather place a load a piece of bronze than a piece of steel.

As Clint Eastwood would say "A man has to know his limitations".

I suppose it would depend entirely on the application....if it aint broke dont fix it comes to mind. Im not sure who said that.  Laughing it would make for easy repair if one had lifter problems later.

If you are not class limited, why would you spend the money on a stock block for bushings?
