No that cam is not choking your heads off. The AFR 205's are made for street performance not an all out top end drag queen which is what a 346 pushing 500rwhp is.

You can go bigger and pick up some top end but you will effect your driveability.
BUT to get 500 rwhp those 205's need to be worked over and even then it would be a max expensive effort.

We can grind you a cam that makes sense and will give you some more top end but I doubt you will hit 500rwhp. People who have hit 500rwhp in a 346 either went solid roller or TFS 215's and a big cam. BUT your talking about a $4600 top end on a factory 346... $2450 TFs 215's + $450 rockers +1300 for prted FAST and TB + $400 for cam. Just doesnt make sense money wise to me. I'd go with a bigger bottom end and keep your heads and make more power as well as having it be more streetable.
