At this point, nothing will be good. "U" shaped upper timing cover, valve cover, front main, vac lines... all will leak. Even the three and four way connectors leak. I picked up 0.5" just replacing a few of those.

Do the boot under the throttle body too, they leak. I'd do the valve stem seals while it's all apart.

Expect 16.5-19" of vac at hot idle, in park
