It depends on the type/brand of roller rocker. Some will clear but most will hit the internal baffles in the valve covers or the Rocker arm nuts (POLY LOCKS) will hit the inside. If you use a roller tip rocker like the comp cams version you should be o.k., I have not seen any problems or you could get spacers to put between the valve cover and the head for added clearance and they are barely noticable. If you use roller rockers make sure that you have guide plates installed or that the pushrod holes in the heads a narrow enough to keep the pushrods from moveing the rocker arm off the valve tips.
