Rocker Stands For Magnum Valve Train??

MD, that's why I was looking for pics...lol. You just need some machinist's dye. You could probably buy a can from any local shop. Or clean the parts well and I'd bet they will make a visible mark anyway. If the rocker is centered on the stem at mid lift, you should be ok. Recall these are 1.6 ratio, not 1.5. So the sweep will be greater.
