Both methods work. Whatever is your preferred method sub assembly or piece by piece method is a choice. No where in the rebuilding books by Wayne Dempsey nor Bruce Anderson mentioned the preferred method.

I fully agree in removing the cam tower/cylinder heads assembly as a unit specially if you are under time constrain like in a race event to get the engine back on the car for the next run. We are talking about engine assembly after an engine rebuild.

In my case, I find it too strenuous and heavy to lift the cam tower/cylinder heads/cam shaft/ etc. by my self without using some sort of a lifting device. For me, it is more practical to do it piece by piece. The decision which method to use is all yours to decide. The so called professional or expert engine rebuilders often come up with techniques or procedure that novice or non-expert like us would find more challenging. A good example is dropping the 911 motor leaving the transmission in place. For bragging right yes.
