Thanks for your reply. In any event, how did you determine end play? Did you just put it together and see that the button was too long, and then revert to Comp Cams Tech, and then to the shorter button? How then did you verify the correctness of that button?
My biggest problem now is assessing the size button required.
I think I will probably use play dough in place off the button as a gauge, and then grind the button to fit (as Summit advised).
I wished Chevy had a "peep hole in the cover to gauge through. I have even thought of putting one in myself (in my alum cover).
Thanks again,

Fred I had a similar problem with the button on my small block roller cam install. I found out that I had the wrong button. I don't remember the particulars but there are at least 2 buttons with different lengths. I found this out when I called Comp Cams Tech line to ask what I was doing wrong. They gave me a particular part number to order. Possibly the same situation exists with a big block. Hope this helps.

I am installing my first roller cam in a pre roller bbc and could use your advice. I am a little hung up on the checking/setting of cam end play. With the new chain installed there is no back and forth movement of the cam. I suspect the new (tight) chain is holding it from moving. So, how do I check it? I have thought of determining the end play without the chain installed. Will this change the reading?
I am using a steel button with roller bearings and it looks to be about
1/16" too long (can't close the (aluminum) cover). Summit suggested I
gradually grind a bit off the front of the button til I have the
desired (estimated) .004-.010 clearance.
I have thought of installing the cover using some silly putty in place
of the button as a gauge to determine how long the button should be for
my application. If I could get a good reading I could then match the
button minus the .004" clearance.
I am using an aluminum cover and note there is a rough slightly raised spot where the button will be. Should I grind this down before I start grinding on the button?
I would appreciate any comments/suggestions on this.
Thanks,
Fred
