Thanks for the alternative procedure. I am using aluminum heads; does the mag stand attach to the head or block?

Hi Fred,
If you want to check your valve to piston clearance you could always remove
the valve springs from the intake and exhaust valve on one cylinder and
install a pair of "checker" springs in their place. Then, on that cylinder
install the pushrods and rockers arms, set valve lash and then slowly rotate
the engine by hand. Every so often you can push the valve down into the
cylinder to see what kind of clearance you have at that point in the
rotation. Of course, you would need a dial indicator with a magnetic stand
to accuratly measure the clearance, but those can be had for less than $30
if you shop around. It's better to be safe than sorry. HTH.

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
