You mentioned that you found top dead center but you haven't said that you've verified it was top dead center on the compression stroke. Like F2 said, you need to verify which stroke it's on.

If you doubt that you are at TDC on the compression stroke, then rotate the engine by hand while watching the #1 intake pushrod/lifter/rocker arm. It will open and then close. When the balancer hits 0 after the #1 intake valve closes, you are on the compression stroke. You can't go wrong by just tightening them down as they have a non adjustable valvetrain. Sometime the lifter will pump up with oil and not release fast enough when you crank down on the rocker causing the spring to compress. It will eventually go down. It usually only takes a minute or so.

The cams need to be set in relation to the pistion. The Piston doesn't care if it compression or exhaust. Set #1 Piston at tdc. Then index the markings on the cam gears . If this is not an interference engine then you are free to rotate the cam with the heads on. Once set the timing chain keeps the rotating parts rotating in squence.

Since the cam and timing chain set have not been touched, just torque down the non adjustable rocker shoulder bolts to I think 35 ft lbs.
Correct, but can't do or see that until the rockers are installed.
