3) The metering blocks are also different between square bore carbs and spread bore carbs BUT the metering blocks interchange between the 650 and 800 spread bore carbs once you change the Jetting and Power Valves.

4) The Dual Bowl Fuel Line is also unique to spreadbore carbs.

5) All of the spread bore carbs use the "Johnson" (a Holley VP's) primary/secondary double pumper linkage design.

You are right. The 4150 bowl will not fit the spreadbore carbs. The hole is just a little off. You wouldn't happen to know what part # those spreadbore bowls are. My book says N/S. Which stands for not serviceable. Must be a typo.
