Valve spring swap, air to the cylinders?

I need help.. i dont think i can get my air adpter into all the plug holes due to the pacesetter LT's. What do you guys use to get to all the plug holes? I figure it's easer to ask and alot faster than figuring it out myself. I want to hear this thing run soon. thanks, Curt

i just moved each cylinder to top-dead-center; if the valves fall down they don't fall far enough to drop out.

i also had this problem when i did my cam swap headders would not let me get the air line to all the cylinders so i just rotated the engine to tdc for that cylinder to keep from having a disaster if i droped a valve. i then used a pen magnet to hold the tip of the valve while i removed the keepers then let the valve sit on the top of the piston while i removed the spring and put the new spring in place. then use the pen magnet to hold the valve all the way up while you replace the keepers.

Do TDC or TDC with some light rope pushed into the plug hole.

The magnet and the rope will work great. i've used rope before, but the magnet is thinking outside the box. Or outside my little tiny box...............
