In California has anyone bored n stroked their 454 put in mild/RV cam and refreshed the heads (new springs and valves) and passed the sniff test portion of smog?

I have a 1980 Crew Cab 1 ton with 454. No Cats, dual exhaust a a cross over exhaust. I still have the smog pump/air injection and charcoal canister in place and working. The heads are 049 oval port. With a vacuum advance and Q-jet carb.

I believe I have a cracked head casket. It got white smoke out the tail pipe
