The standard rocker has a 1.6 ratio. I have seen it written many times that the AMC heads must be machined when installing roller rockers to prevent binding. Is this only necesary if you use guide plates or is it always required? I am asking this because many advertisements for the new Edelbrock aluminum heads contain a footnote that rececommends teh use of hardened pushrods and roller rockers with the new heads. Edelbrock has stated that the new heads are designed to be used with either the original stamped steel rockers or 1.6 ratio roller rockers. IT seems inconsistent.
Also, for those that have instaled roller rockers, what brand and type did you use?
