You have to pull the cylinder and piston on the broken one to get to the stub.
Do a valve job while apart.
Upgrade your cross pin on the clutch fingers

You do not have to pull the piston. I am not sure why Bruce is saying this. I think he is pretty busy, which is a good thing.

You can pull the cam and extract the entire set of three heads coupled to the cam tower if you don't want to do any thing else except change lower studs.

Boat tailing the mains is a full rebuild. You need to eyebrow the pistons as well to gain full benefit of minimizing wind related restriction. For a 6,500 rpm street car? I say don't bother.
