360 LA installing Promaxx Aluminum heads

My kit arrived today. Looking at the card it appears that the stock primary jets must be 78's as that is the one missing from the kit. The 60/52 rod is also the one missing from the kit. I am going to Moparfest this weekend, which is about a 1 1/2 hour drive each way so it will be a good test. I don't want to pull the carb completely apart in case I mess something up and miss the show, so I will install the 64/56 rods and see how that works.

IIRC the stock primary and secondary jets are both 80. I'd start by swapping in the biggest metering rod as you don't need to take it apart and risk tearing a gasket to do so. Just be wary of that dang E clip on the choke side. I got pretty good at removing and reinstalling it.
