I installed the heads this morning and then the kids put the valvetrain parts on. My son's favorite part was glopping on all the moly paste and red goo antiwear ointment to the cam, lifters, rocker arms, push rods, valve stems, and clothing. If it involves making a mess, he's happy to assist. My daughter on the other hand had just finished her nails and was quite content using the clean breaker bar to turn the engine over while I adjusted each rocker arm.
Normally a Pontiac is a set to 20 ft.lbs. with a non adjustable valvetrain but the shouldered rocker studs were previously replaced with a set of 7/16 x 20 Big Block Chevy studs with no shoulders. That allows for a more precise individual adjustment.
