Is anyone running these without bushing the lifter bores? Being a cutaway style lifter, I wasn't sure if it can be done or at what lobe lift the oil hole becomes exposed creating an issue. In my case, I'm putting a set of 440-1s on a low deck so I was looking to clean up the pushrod angle. If it's not a big deal, I've had good luck with the solid body 829 lifters from Comp. I only plan to run a lobe lift around .420-.430

I run the 87019s in a MW Victor headed RB, un-bushed. If I did it again, I would just clearance the heads a bit more for pushrods and run the 829s. I run a .421 lobe lift solid roller. Once together, when hot, had around 55psi at 7K rpm and 10psi or so after a pass at idle. I ended up partially blocking the oil supply to drivers side lifters and now oil pressure is back to an "acceptable" pressure at least for me. Been together now just short of two years with many passes and some street duty. I don't think I'd run them again unless I had too. Funny how they are cheaper than the 829s

Here is a link to a thread of another member that was having pressure issues and also showing how I blocked oil supply to lifters

Thanks for the info and sharing all the pics. I wish I had everything here to see just how bad the pushrod angle will be with the 829's.

I used them in a 400 block with Stage 6 heads. The valve lift was 660 & the oil band was still deep in the lifter bore.

I ran the Comp 892 offset roller lifters in a 400 block with a .460/.450" lobe lift cam with no problems. Check if the only difference is that the 892 add pushrod oiling.

And with the 440-1 heads, I had to grind a couple bosses in the 400 block to give the push rod clearance.

No pushrod oiling on the 87019.... They do have a very small EDM? hole to oil the bearings.

Thanks for all the pics and info. For those that have done or seen both the 87019 and 829 lifters, how necessary are the offset lifters with the -1 heads for the lobe lift I intend to run (.430ish)?? I mainly brought this up since I have a line on a brand new set of 829s for $340.

take your pick. either go with the offset & depending on your application you'll have clearence or stay with the std lifters but spend some coin getting them clearenced. i was given a set of -1's to clearence for a guy running a solid cam. it took a bit to get it right but it sure was close to the intake runners. it can be done.

I think offset is certainly the way to go since I won't expose the oil band at the lobe lift I intend to run. Might as well clean up the pushrod angle and this is going on a low deck so I may have to clearance the areas Jim mentioned. Thanks for the responses everyone.

Might want to talk to Mike at
http://www.mrlperformance.com/
Im planning on running his lifters on my 440-1 headed low deck next year alot of guys on fabo talk very highly about the quality of his lifters.

The MRL lifters look nice too. Any idea if he offers a rebuild service on them when the time comes?

I believe he does but please dont quote me Mike is a mopar guy thru and thru,and his are cheaper then other roller lifter of any kind of quality
Heres a couple threads over on fabo maybe some of your questions can be answered over there.
Theres a company he uses also that has a product to help fix ma mopars geometry issues with ones valve train the company is b3racingengines@comcast.net the kit for 440-1 heads with harland sharp 1.6 rockers $180 shipped in the states
