RE: which AFRs for my 94?
You technically dont need the 185s for a 331. They just help it to come alive better! Heck stock heads would work on a 331, but they would really limit it as far as power output. I would say go with the 185s if you can afford them, and get a nice big cam. If its a 331, then the pistons should be notched enough to run almost whatever you like.
