Tim - you seem to know how to 'FIND' stuff .......the lifters are Sifton Max-Axle.......got any ideas ?
Well........I have some ideas but you aren't going to like them......lol
I recently had a discussion about lifters earlier this week.....the topic however was primarily on the TWIN CAM Side.....the conclusion after a bunch of research is that the OEM "B" Lifter works great for most applications involving the TWIN CAM.........but we of course are talking about EVO Lifters here......the "OEM" EVO Lifter is great as well....with no need to change them EXCEPT FOR one particular reason.....the side walls of the lifter rollers are designed in such a way that it's possible if one were to fail that the result could be catastrophic in the sense that there is no side wall on the roller area in which case the individual "needle" bearings could "potentially" find themselves at the bottom of your cam chest....and running through there ever so politely....ouch......bottom line....it's a good idea to change out the OEM lifters especially when doing upgrades.....
So now what should one use......the answer quite simply is that there are others here more skilled in such an assessment than me, even though I realize this wasn't really your question.....but we are here to offer one another input and the grace to enjoy one another's decisons....here are the lifters I installed when replacing my OEM CAM:
Big Axle Powerglide™ Hydraulic Tappet For ’84-’99 BT, ’86-’90 XL, ’87-’90 Buell®, Single¬
Standard O.D. is .8425”. Individual tappet weighs 149 grams. This tappet replaces and surpasses H.D.® No. 18523-86 and S&S® No. 33-5341. Use with 2272-IS Instruction sheet. Total Hydraulic Lift: 0.200” THE POWERGLIDE™ ADVANTAGE
Longest valve train engine life. Produced from billet bearing steel. The same high quality steel our shafts and crank pins are made from. The best made JIMS® big axle roller. The ultimate in hydraulic control system, performs better under both the lower and the higher R.P.M. limits, and high spring pressures. A true centerline for roller life and exact cam timing. State of the art pushrod seat, machined with the same segmented parabolic cup as the JIMS® roller rockers. Helps eliminate pushrod whip. Engineered on a state of the art cad system, and machined in some of the world’s most accurate precision computer controlled machinery. Hand fit hydraulic unit to a running fit of .0002”, with ultra precision air gauging system. All hydraulic units are tested 100% for function under a simulated pressure test fixture. The best warranty policy in the industry.
Powerglide™ tappets are capable of the highest rpm a Harley® can safely turn (about 8025 r.p.m.) at a valve lift of .700”, with the right valve springs, valves, cam, oil, etc. We recommend using with JIMS® tappet blocks No.1094. It is not necessary to use a limiting travel washer in "PowerglideTM" tappets. For ALL OUT performance use a hydrosolid tappet.
JIMS BIG AXLE POWER GLIDE HYDRAULIC TAPPETS JIMS PART # 2456-1 (BRAND NEW). FOR 84-99 EVOLUTION : REPL. OEM #18523-86, POWERGLIDE TAPPETS HAVE A MICRO-FINISH BORE THAT ALLOWS A RUNNING FIT OF .0002". THIS TAPPET REPLACES AND SURPASSES HD PART # 18523-86 AND S & S PART # 33-5341.
• Powerglide™ tappets have a micro-finish bore that allows a running fit of .0002”
• Big Axle™ rollers are designed around three working parts
• The outer wheel/roller has a 27% greater wall size — less harmonic distortion for better tracking of cam lobe
• Pin bearings are decreased in size by 12%, which increases rpm for more precise tracking
• Axle size is increased 36% and doubles as the inner race, so the pin bearing and complete roller assembly now
rotates around the axle instead of an inner race, eliminating all possible movement in and around the axle
• Made in the U.S.A.
For 84-99 80” Evolution; Repl. OEM #18523-86

From jenni in 2005.
Another brand most are familiar with would be a set of S&S Lifters.
On my bike one of these two brands would be going in.......so this is all I know about lifters.....perhaps others here will have more input as to what to do......but if it were me.....well....lol it doesn't matter if it were me....lol as "me" already replaced my OEM EVO Lifters with the ones above.....which speaks to how I feel about lifters......
I know you were asking how you might find an instruction sheet.....but I am way back at the beginning of this decision that says....the brand you have chosen wouldn't be my choice. Every decision I make on my bikes always seems to be a painstaking decision....lol....meaning that I do tons of research before I do anything just like the rest of us here, we all do research each and every one of us......and at the time for me in 2005 what I chose to put in seemed to offer me personally the most security based upon the answers I received.

Tim
