I have two single matched Rochesters on the typical Offy intake. There was a intake/Fenton exhaust clearance issue, but they were miinor and corrected with a little intake grinding.The biggest problem was getting my linkage to work correctly without binding.There are better linkage systems now to use.However,if I were to do it again I would seriously consider the 2 barrel Holleys that Tom Langdon sells on Stovebolt Engine Company.They have very smooth operation and adjust very easily.
