I would say your probably fine with your current mileage, BUT if you race it then there are certain things that I would do to ensure longevity. Like you mentioned the rockers are a weak point and che trunnions are a good investment as well as a good oil pump. I would recommend the melling 10355HV with the higher compression spring for sustained high rpm. I would also recommend plugging the oil bypass relief valve in the oil pan. There's a guy I read about that kept rebuilding his engines and swore he was getting trash in his bearings until he plugged it because of the higher rpm that he was running and which can be a double edged sword when running a high pressure oil pump without plugging the bypass valve because when you go over 50 psi the oil bypasses the oil filter and goes straight to the pan. And some racers say that you want all the pressure you can get at high rpm. So that's something to think about. And if your running a different camshaft then you would want a quality valve spring and lifters to go with your trunnions. You may also want to look into some tranny and oil coolers too like the mishimoto oil cooler and the tru cool 40k. Just my $.02
