Folks,
Thanks for the info. I just finished grinding .033 off of the end of the roller button to fit it. I had tried to use play dough (too gooey) and then used an extra aluminum button as a preliminary (easier to grind) gauge. Once I had the alum fitting I matched the roller to it (I actually hack sawed off most of the excess). I had what I thought was the right amt of play but once I buttoned it up the cover the cam lost it's to and fro movement, which it had with me holding the cover as tight as I could against the block. The engine turns over easily by hand though so I guess all is well.
Here's a related question. I am installing an Edelbrock Performer RPM cam. This cam has quite a bit more lift than what I was using, and I am wondering if I can avoid checking piston to valve clearance (I really don't want to pull a head). My block is stock but for a .030 overbore, I am using flat top pistons, and new Edelbrock Performer RPM heads (never been milled down). I know the prudent thing is to pull a head but I recently read that Comp Cams was only recommending this check for radical street and racing cams.
Thanks again,
Fred
