Thick wall pushrods to go along with those shaft rockers also. You can never have too strong of a pushrod at high RPM. It's all about column strength. Trend and Smith Brothers build some of the best money can buy.

Ti valves wouldn’t hurt. These are old enough to buy me a beer.

Lol.....living here in NC close to Charlotte and NASCAR engine builders, I've always got used cut down Ti valves.They have always been cheap and easy to get for decades.
