Any mod motor guru's in here looking for the specs on an old set of Cushman's that came in the car the part number between the lobes is 312944. Also have a few 2v valve cover questions Would removing the valve cover baffles cause any problems? As well as deleting the factory pcv to run a catch can? I know the can and breathers have been done continously but i was told that's a big problem? Also I bought a set of valve stem seals for a 2v are they interchangeable to use on per say a 4v ? Head gaskets shouldnt matter as well correct?
