spark plug installation torque
I'm trying to do things more professionally these days so I routinely go to my handy torque specification sheet that I downloaded from the web for an Olds 455.
It wants me to torque my spark plugs to 30 ft.lb. This seems like way too much. I've got a 71 455 with iron heads.
I'm ready to put them in by feel like I always have but I'm sure I've never tightened them to 30 ft.lb. Is this accurate?

I first heard about indexing on Musclecar Garage. Should be easy enough to do on a wide open 350, 425 or 455. Any idea how you would do it on a V6 when you can't see the back spark plugs? Hmmm, ok I just remembered, you use a mirror tool, but it's a real PITA to work on the back plugs of my 3800. You have to take off a bracket just to get to one of the plugs. Don't forget that if you're indexing, you need copper washers to crush or the plugs won't seat and seal right.
