I bought a set barely used and want to see if I have the old or new style.

Here you go.

Didn't take a close up of the pin hole sized bearing oiling hole in the lifter band.

Thank you!
So, it appears you haven't modified these.
I was hoping to see how narrow this "relief" can be to work effectively.


Nice abs btw!

Ugly?  Easy now -- that's my baby and it's got lots of unique character!  When I drop that built 445" stroker in it you won't have any time to "pull over to let me pass" because I'll have already blown past you when you figure out what the hell was that loud noise behind you . . .

Not modified.  I still need to clean them and soak them in oil before I drop them in and see how much room, if any, I have to relief them.  Stay tuned.

That picture was back when my wife and I were dating and I had gone on a wake boarding / beer drinking trip to Lake Powell with some buddies.  Back then I ran all the time, and had just started hitting the weights.  I need to get back in shape.  Embarrassed

If it helps, here is a "modern" 838 with the oiling mod next to a comp SBF solid lifter:

Ok, I must have the older style. The groove in the side ends higher up the body.

Older style of the 838 had no groove, although it was often added:

I don't know why I didn't think of this right off the bat.    But when I checked for clearance I realized I can just modify them like shown in the pictures of the newer lifters and keep the cut below the round hole in the body above the lifter band.  So, yes, I do have room and will extend the lifter band upward.  I should have just done this from the beginning.  Embarrassed

You can mod them, but if you can see a portion of the lifter's oiling band through the block's cam oil passage throughout 360 degrees of cam rotation, it is not needed. 

In addition, if you do mod them, be careful that the new bevel is not open to the lifter valley at anytime during the cam rotation or else you will loose oil pressure.  Be careful of metal chips on those new bearings.

The clearance I was checking on was seeing how much room I have to cut the lifter without it going above the lifter bore at full lift on the intake and exhaust lobe.  I will be taping up the lifters so zero metal shavings can get in anything.

To check it right, each corner of the block should be verified that the oil band still intersects the oil passage in the block.
The passages are drilled half way through the block from each side of the block.  I was surprised at the mismatch front to back on my 351w block...
