In this case the pushrod length needs to be such that the hydraulic lifter pre-load is .075" +/- .025" You will want to check to see if the rocker roller tip is running across the center of the valve stem tip. If not you will need to shim the rocker pedestals to get the correct geometry. T...

If you can't jet any higher without making the midrange A/F too rich then you will need to drill the PV passages.
