Can anyone tell me what is the largest valves that will fit in a stock cummins bore? I am looking into a set of 1.870" intake valves and using the stock 12 valve intake valve on the exhaust side which I believe is a 1.775". Will these fit without notching the bores? Any help is greatly appreciated.
