Like what has been said if you did you can seal it off from oil without the sleeve job, only if you have ground thru both common walls will you need to sleeve and seal to keep the vacuum within each port so to speak.

Well, I only knew of one place where that happened. But I know they are all ground fairly thin. Because I only knew of one place I was concentrating on the other stuff. But I now know the valve seals are good. I'm also now sure that the rocker studs are sealed. So it's what was left to look at.

I only know of one breakthrough. But I also know that when walls get thin porosity can be an issue. So I'm open to the possibility that it's in more than the one place. I know I have oil getting on more than one hole. That's basically it.

Sounds like this tube idea is a bust if Paul is telling me they use 17/32" and have to ream the inside. Ah, poop. I just liked the tube idea for ruling the headbolt holes out completely since this is driving me nuts.

Right Stuff RTV ordered.
