What Size Valve Cover Breather?

[1993-Sierra-Z71]

What size breather do i need? im taking that choke collar off and im going to put a breather in. also will my stock air cleaner housing hit anything when it sits that lower? i plan on getting a TB spacer soon as well.

If you put the air cleaner on top of the tbi unit I think part of the throttle bracket is in the way look at the writeup on here about the ultimate tbi mods pretty sure it was on here where I read that

Do the TB spacer any you'll be fine. When I had the open element on mine I had to use a 3/4" collar and a lower pan that didn't drop at all. The valve cover breather is 3/4" too.
