I ordered intake, valve cover and tb gaskets. Damnit, just checked shipping and I actually never checked out the parts. I did on lunch and now I wont be able to put it all back together this weekend. oh well

Trochoidal - That pic is from an old engine where the machine shop was plugging the DOD holes in the valley. As for signs of the intake bolts bottoming out, I didn't look and don't remember any chamfers looking shiny. I'll check again this weekend. I would think the intake manifold bolts are specifically made and used so the metal collar does tighten down onto the head. I could always pull the collars out and use reg bolts torqued to spec.
