Hello, I finally took my rocker arms off the shelf and took a better look at them. Turns out there are 12, not 6 rocker arms. Also, the instructions say they are for powerglide cars with hydraulic lifters. Why would there be rocker arms for exhaust valves, too? Thanks.

a 30,000 mile UNMOLESTED original, now my daily driver! Original 6 cylinder with a rebuilt '66-'69 Saginaw 3-speed Overdrive. Synchro low! Otherwise, everything original down to the spare tire. Interior is like new. Needs paint, but absolutely zero rust.
