Small side quest, I had to pick up a special socket to Allen adapter that can angle, to be able to get a torque wrench on the intake.

And I love the fact that Steve Pasteiner is willing to put them on display. They came up with a cubic-inch 4. The valve cover also becomes a problem, all these clearance issues made for a solid week of measurements and test fitments. The valve size increased as well, to 2. GM would use all their reserve stock in other cars until they were gone.
