Unless the block is very important to you i.e. lots of machining already done, good expensive block or has some seriously loose lifter bores, I would just start with a different block. Bushing bores is a very expensive operation, and judging by your other thread, I think your oil pressure is more then enough as it is. If you really want to, you can tube the lifter gallery- much cheaper, but MUCH more time consuming...somewhat crude, and a [censored] to do, but it will increase your oil pressure.
To be honest, I have asked about oil pressure related stuff many times, and based on what you said yours runs at, I think your good...Im no expert, but thats my 2 cents

One other thing about tubing the block... that kit is discontinued so you better know someone with the whole kit(its 2 kits) that will loan it out.. I loaned my out a few years ago and it never came back

I have never worried about saving and engine after a lifter comes out--if you ask me it is a little too late for that kind of hope and...you block the oil to stop the 16 leaks around the lifters--OK spend $900 plus to do it or...just plug the one side with a 2 cent drive in plug on drivers side and leave the other side alone --now you have spent two cents to stop up 8 of the leaks for a little better oiling--the other $899.98 seems excessive to stop the other 8 I know you get corrected lifter bores etc but really?
The old drill and peen package from Mopar was a joke--You need a drill bit easy available from tool store $20 --that reamer ain't going in those crooked factory holes--then you need $6 worth of plumbing pipe--then you need to grind a round nose on an old lifter--then you have it for less than $30 The lifter galley holes are drilled half way from rear and half way in from front --they meet but if it was a highway tunnel job no cars could pass --it is awful so a drill bit not a reamer is in order--besides if you use the reamer the pipe will not fit in the hole--way too tight--IMO many a good block has been ruined while folks learn how to do that operation--drive in the plug on one side and race your rear end off--easy breezy. Got an R block--going to make giant HP--then by all means have bores bushed--stock block? I think it is bif=ggest waste I have ever seen--

anyone ever bush the lifter bores on a small block? was there a performance increase. just curious if small blocks are in need of this procedure. don't know if its worth the money spent. It straightens the lifter bores and gets them all pointing the same direction. Smallblocks get worn due to that ugly pushrod angle and they wear to an oval shape.
Yeah, it's got a smallblock.

You tap the feed hole from the front main saddle to the driver side lifter galley. Usually 3/8x16 and put a set screw in with red loc-tite. Turns oil off to the driver side lifters. The tubes go in the passenger side lifter galley. A little effort will make the engine stand a lot of abuse and live. All the leaking oil past the lifters will now go to the main and rod bearings instead. You can get really crafty and dam the oil up in the valley and return upper end oil through the driver side lifter galley behind the timing chain gear. Demon engine has all these mods. and 1890 passes and counting. Crank and pistons never out of block from new. 418 c.i. in demon. 587 production cyl heads. 9.68 at 136mph 443c.i. short block

OK thanks. I thought Crabman said tubing was a joke and just plugged the drivers side. What would that be doing with a plug to Dr side and no tube on pass? If you want to see it and read about the tubing its in the MP SB book
