I have a set of 351M/400M heads and want to know if there is any difference between 351C and 351M/400M heads. I want to put these heads on a 351W block. I know I'll have to drill a hole in the intake side of the head for water passages, and I'll have to block off the stock water passage on the combustion side of the head to make them work. Also do these heads even flow better than stock 351W heads(I've got the 2bbl 351M/400M heads)
