Long ago I bought the washers That "Pope" said to use . They are .060" thick. and you are to use two under each PT lifter/ so you end up with .120" total height.
Well I've finally pulled my valve cover to do is PT lifter swap. Since the time I got my lifter spacers, you guy found washers that are the correct thickness of .120"
Is there any problem using two of the washer (.060" each) that Pope was using ?
Or should I buy the new thicker single .120" washer ? is there anything that needs to be done to the washers before installing them ?
Also who sells the washers for a good price / only need the washers.

Remember the shim numbers with Fastenal is in the FAQ section. Back when written the company name was fasteners.

is there an opinion which "side" of the washer(s) should go "up" ..?

IIRC the washers I got from Pope a decade ago - like many/most 'normal' 'flat' washers - had a 'flat' side and a 'rounded' side..

I put 'rounded' side 'up' for both washers ..

Correct, rounded side up .
I've always put chamfered side down in case lifter bore isn't cut perfectly 90°. There is a reason why bottom of lash adjusters are chamfered. Another example of this is with oil pump rotor. Large chamfer goes down in oil pump body for that very reason.

What I do is take a couple thousands off diameter of each washer to make sure it can't ever get stuck in lifter bore. I've been down that road a couple times. Hope you guys are using grade 8 washers or better. Wouldn't use stainless for a couple reasons. Kind of sucks trying to get mushroomed washers out that are stuck in lifter bores.

Yes, PT Lifters and hardened shims and beveled side down, that is the correct orientation for installation. The reason is that there is a lip at the bottom of the bore and you want the washer to sit down in that space, not hold the washer a few thousands of an inch off the floor of the bore.
