Yes they have been out of the .175 for a long time now. I recall reading somewhere that .170 and .180 were commonly used.

I suspect he had these .175's made up special to cover both sizes. I was wondering what size MSA was shipping now.

Schneider is grinding my cam and I have a set of .170 and a set of .180.  If it needs .190 I will just have to buy some more.

Yes, you read that on MSA's website, the .175s were made to cover both sizes.  I'll try the .190s on the first one or two to see where they hit.  If they're too far off I'll order some.  I got all my stuff from Schneider though, including the .190s.  maybe they were getting rid of all their L series lash pads?  Their website says "out of stock until further notice" which to me means they've quit selling them.

From MSA's page " Size Update:
Schneider and the other cam manufacturers decided to have a .175" pad size added, which covers the very common area between .170" & .180" on medium to large lift camshafts. Ask your machinist about the size you should start with."
