My spring retainers also hit. I think my rockers are Mopar Performance, which I have been told were Dick Lady units. I want a stock look, so I have tossed around the idea of stock rockers on the exhaust side only. My car is strictly a street car, so I have also thought about going to manifolds.
I recently put a couple of engines in cars that had "stock" valve covers. 1.55" x 1.88" springs. (Pretty big cams.) One had Mopar/Dick Landy rockers and the other had Stage V's. Both worked fine. The problem is, those valve covers, which "look" stock, didn't come on a car originally. Those valve covers must have more room than the ones that came on a car. If your car is a 68 there have been lots of repop valve covers for those. One of those sets might fit. Might be an easier out for you.
