The 2ndary jets and metering rods are correct. And the pri jets may be if the #'s are 4099. So something is leaning out both the primaries and 2ndaries.

If the car drives poorly on the primary circuit(cruising)and when going wot, look for the things that can cause a lean situation. If you remove the carb, be sure:
1)the carb base gasket opening/center 'matches' the primary bores in the base; you do not want the gasket to be smaller than the primary bores in the base of the carb.
2)set the carb back on the intake without the base gasket and see if the carb fits flat on the intake mounting flange with no attaching bolts.

Also check any vacuum solenoids on the carb do not have vacuum leaks and the same with the vacuum advance on the distributor if it is in use. The correct port for distributor vacuum advance is the driver side front port in the base of the carb.
