Sounds like I might want to split the case and change out or at least inspect the rod bolts?
If there's no real benefit to the 964 cams, I'll stick with my stock cams. I figure that'll save me about $500 that I can put elsewhere if inspection shows something is needed.
Thanks for your input sir. Always appreciated.

There is no way to be sure about the rod bolts. Even in the best of situations, the rod bolt/rod journal configuration is prone to failure. Good used std/std 3.2/3.3 cranks are like rocking horse shyt....impossible to find. They have a failure rate that far exceeds all other Porsche engine configurations.
Many years ago I had a customer in the very same situation. He ignored my advise and rolled the dice. The engine lasted 82 miles. He was so disgusted with his choice that he sold the car with the exploded engine.
