Setting your rev limiter lower than redline will do nothing to help a missed shift if it's a big enough miss.

My engine's built so the rockers are the weak link. When I miss a shift and hit 8400 rpm, the rockers break and that helps prevent bent valves. I think I've missed about 5 shifts in the last 10 years that did damage. In 4 cases only rocker replacement, a 60 minute fix and I usually didn't miss a session (thanks to the JWE guy's doing a quick fix). Once I missed big enough to bend a valve. I think 3 of the "misses" were due to an issue with the shifter linkage that we eventually figured out and fixed.

If you miss a shift and the car runs fine, no reason to worry. Just be thankful you got lucky and keep driving. Done it more than once.
