I should have listened to my engine builder better when he said it time to tear the engine down to check it out.
It has been in the car since 2003

How many runs and miles were on it?
When a car isn't used much it is hard to accept it should be taken apart, inspected, and freshened. But depending on the power, parts used, etc. it could be a good idea.

It is easier to accept that a 700 hp engine that makes 150 passes per year needs to come apart every 2-3 years. Sometimes every year is cheap insurance like on a new combo/build to make sure everything is wearing properly. Valve springs on big roller cams, roller lifters, even aluminum rod, etc. may not last very long and replacing them often is cheaper than letting them break.
