If one were building a short stroke race motor that can reliably rev to 9200, would stainless valves still be a good choice or should one be thinking hollow stem or titanium at that point. Letís take cost out of the equation for now and focus on performance and reliability.
At 9200 you are around a 8 hr service life of the valvetrain. You are at the limit for a 2 valve head regardless of material used. I have used stainless and as long as EGT is under control it is fine. Going to a lashcap/ non adjustable rocker arm will help keep things stable.
