We apologize but there is not a choke port for warm up of the older style choke spring on these intakes and the only other option would be an electric choke if the older carbs can be converted to electric.

This manifold does NOT allow sufficient clearance for an HEI distributor. It will accept an electronic distributor such as Speedway’s 44710070, 91030000, or the Joe Hunt mag look distributor number 91012550.

This Offenhauser 3 deuce intake has provision in the front adjacent to the thermostat housing to run the old style breather tube number 91017441 along with cap 5502060. If this provision is plugged or capped the only other option for crankcase ventilation is valve covers such as 91017161, 91017162, 91017110, or any other styles offered that accept breather caps. It is not recommended to drill and tap the intake for plumbing of a PCV valve. If desiring to run a PCV we would suggest a carb spacer plate with plumbing capabilities and run under the primary carb to a valve cover with the PCV valve.
