Exactly. Pulls about 10 inches vac at idle. 1 turn out, all 4 corners. Found out today, intake STILL sucking oil through the valley. Couldn't believe it...
I guess the Hughes method of intake sealing isn't exactly "perfect". Today was the 5th time I pulled that intake this season...........FINALLY I think I got it.
All the clearancing and painstaking crap you go through to build a motor, sealing a friggin intake shouldn't be a big deal. Man. Once you mill your heads, it's a crap shoot.
