The smaller bore motors of A-series range of engines have a cylinder head with valves that are spaced much closer together than the 1275cc. Thus if you have a 948cc or a 1098cc cylinder head then you probabaly can make use of these special 1.5 ratio roller rockers that are setup for the small bore heads. This is a full roller set and thus has roller bearings both on the rocker shaft and on the tips of the rockers that contact the head of the valve. The full roller set has less drag (more horsepower) and better response time then those with bushes on the rocker shaft.

The new generation of short period, high lift cams have been developed to give the best results in large bore engines when used in conjunction with 1.5 ratio, hi-lift rockers. For the small bore range, the stock 1.3 ratio is optimum. In certain instances ratios of 1.7 to 1 are of benefit - but is really only applicable to fully developed race engines.
