2 questions about 305ci cams?

I have a 91 RS Camaro. It has a 305ci roller motor bored 30 over. 4200 miles on motor. It has Brand new heads but they stock. But the valves are literally just a hair bored as well. It has stock springs. What is the biggest Cam i can run without building the heads stronger. Lift and duration is what i'm looking for.

Also what is the stock 305 cam lift and duration? Thanx guys

I think that you have the Peanut Cam. Do a search.
