Is this cam a stupid idea?

Ive got a stock bottom end 5.9 mag with ported factory heads, had the stock cam reground to 242/[email protected] .550/.550 w/ 1.5 rockers, on a 110 lsa. Sounded great, pulled like a freight train, and was pretty well mannered for street driving. The converter and tuning plays a big part in the streetability factor.
