Off-season engine freshen

I typically go around 400-500 runs before I "freshen" up my engines. I always tried to do it during the off season. A freshen up for me is usually includes new rod and main bearings and gaskets as long as everything looks okay. When I used to race weekly from April-Oct that would be about every 2 years. Now that racing is a lot lower on my priority list my last refresh was 2 years ago and I only have about 75 runs on my combo since. At this pace I figured this freshen up will probably last me 10 years. I do run a milder, lower maintenance combo for today standard those with 10.5:1, running on pump gas, with a .557 MP flat tappet solid cam. Shift at 6,000 and mainly only run 1/8th mile anymore.
