I'm doing this exact same thing but have a question for you since you did this already

When pulling the motor today I noticed the cam tower covers, plugs, and the end caps are different between the two motors.

Here's the end cap on the cam towers from my current 4.5L engine.

and here's the end cap from the 4.7L engine

Since I'm planning to reuse my 4.5L cams in my 4.7L engine because of the higher lift and longer duration, here are the questions:

Will the 4.5L cams fit properly into the 4.7L cam towers with the 4.7L cam tower caps, or
Do I need to use the end caps from the 4.5L cam towers with the 4.7L cam towers, or
Do I need to reuse the 4.5L cam towers complete and if so, do they just bolt onto the heads of the 4.7L engine, or
Is there some other magic combination I need to do between these parts to have it go together correctly?
Also, which cam followers/lifters should I use - the ones that came out of the 4.7L head if the 4.5L cams are being used with those, or the ones that were working with the 4.5L cams in the current engine, or does it not matter and just use the ones that look to be in better condition?

Thanks
