You all must under stand that a performance based build wears out much faster than a stock engine.
I have found d over the years that optimum or highest average torque is achieved between 2&5krpm is found with 1.3 to 1.35:1 rocker ratio. Certainly higher ratios give more top end hp but usually at the cost of shorter service life in road applications. Use the minimum spring weight you can get away with and only enough rocker ratio to give you the biggest area under the curve for the cam chosen.
There is nothing stopping you using 1.5 rockers with cams for the street, but you must perform regular lobe lift checks. As soon as wear is found change the cam. The cam and followers in my experience when usesed like this become a regular service item. You need to budget for this when you spec your builds. Swiftune makes some of the best components available and there camshafts are very good. Just consider the mechanical stresses involved with the whole system including what you actually want in terms of service life from your engine.
