Correct cap for draft tube ventilation system: Jim Carter ME738..........58/59 seems to be years that the cap was in the middle. Other years on the end. Aftermarket: on the end. 1954 an earlier valve cover had breather slots and non vent cap. 55-62 vent cap, no slots.....then the PCV (some info per J.C, although his blog says PVC)
My 58 Delray coupe with a 235 3 speed setup had a center oil fill cap and an offset air cleaner, both of which just barely cleared the hood. The pickups had considerably more room above the valve cover and the carb. Jerry
