Retune my entire carb after installing new heads?

Thanks. Got to start somewhere. Actually I don't have to take the bowls/blocks off to change jets, I've got those little removable plugs. Only thing that comes out is the gas in the bowl :)

I got the idle AFR back by just opening each corner screw about 3/16 turn more... so my plan is to change jets first, see how it drives and AFR readings, then mess with the small orifices. :thumbsup:
