I've had a couple of non Prime folks ask me this and like to grow my knowledge base on this topic to sure with them.
The only benefits I can see with regards to doing block work are:
1. blue print and balancing
2. lighter pistons (for NA applications 4032 forged pistons are the lightest)
3. increasing the CR (500HP~ 911 4.0 are at 12.6 CR if I recalled correctly)
I like to know with thermal coatings, valve job, port clean up, and port/manifold matching what else am I missing?
