Kit, your cam is not radical and your spring pressures are light. You didn't mention what lifters you're using, but I would be doing a lifter inspection or even a replacement at your mileage level.

In the future, if you do a rebuild, there is absolutely no reason to run a solid roller for this type of build. What you have could have been easily accomplished with a hydraulic roller that could go 100000 miles without issue.
