Also, to Goose, I am trying to lkeep the valve cover height down as I am trying to be able to fit the stock valve covers between or under the stock brake booster. I currently have a whole new brake system, but I am trying to avoid having to buy a smaller booster just because of the valve covers [/quote]
Think you misunderstood, that exactly what they were built for... Stock covers but running taller roller rockers underneath. I too have a full size booster and have the same clearance issues. These are a $25 fix to solve that issue
