As a man with a "hopped" inline 6, Welcome to the family! Anyway, to buisness. With a 194 you have a small six there. Dont over-carb the poor thing, or it will dog. I would reccomend about a 3-400 Edelbrock 2 barrel if you can bolt it to the clifford manifold. As for the exhaust manifold question, it may fit with the new intake. May advice would be to simply hold it parallel to your current intake. If you have overhang on the mounts, it wont fit. If not, chances are it will. However, if your trying to get any real power from the motor, headers arent a bad idea anyway. Remember, you have something different. Treat it as such
