You have drug out a simple rebuild this long. Over analyzing 90% of it. Now when you want to swap the cam shaft you won't do it right?
Just my opinion it may be worthless.
The length of time for this project has zero to do with the issues, or how to replace a camshaft without removing the head.
Whether I over-analyze the crap out this rebuild, or do it as blind-folded retard, has nothing to do with the issues.
How I do it, or doing it "right" is subjective.
Thank you for your input.
