I would consider buying a 'split ratio rockerarm set. 1.50/1.60 ratio.
Or hook up with a buddy who also will be buying rockers and order a 1.5 ratio set and another 1.6 ratio set of the same rocker arm.
Install the 1.6's on the intake side to quicken the intake valve action (rate of effective valve lift) within the same 282deg seat running duration combined with increased peak intake lift of .496" the 1.5's are fine on the exhaust side keeping the lift within a range that the crane springs will easily handle and give better valve guide life.
The 1.6's will have the most effective gain on the intake side.
