so i decided to test the gear calculator
If it's an AP2 (looks like it from your sig), you may be OK if you kept the mechanical peak rev down (search for threads, but something like 10K comes to mind). The AP2 gives additional margin and as far as I know doesn't exhibit the valve retainer cracking issue. A compression and leakdown test may be in order.

According to Billman, an F22C will bend the exhaust valves first, and will never stretch the retainers like the F20C, and if you'd bent an exhaust valve the car would not be running properly.
Is it running OK?
If so I don't think you have anything to worry about.

You rev matched to go into 3rd and you did.
