Full roller rockers. iron head 3.1?

[23TrackroadsterV6]

I bought a set of Comp Cams full roller 1.6 rockers, 3/8X10M rocker studs off of Ebay for a decent price. I am now doing some site reading and think these might not work on an iron headed 3.1? I know the studs will work and I already have a set of stamped 1.6 roller tip rockers that will work. I also have a question about water pump and timing cover issues, but I'll address that in another post.

Yes the studs will bolt right in. You can then use any small block Chevy rocker arm that is designed for center bolt valve covers. They must be of the center bolt valve cover style or they will be too wide. In fact I know the Comp Pro Magnum full rollers for center bolt valve covers are just a but too wide to work. The Crane Cams gold roller rockers work fine.
