Good reading there. Most of the information regarding cams and heads is dated, but it has the core fundamentals.

I don't have that second book, but it was published in 2006, so it probably has more current information relating to cam/heads.

The Reher Morrison book is an awesome reference and worth every penny.
Keep in mind that you're going to need some specific tools to check tolerances when building the motor.
Inside mics for main/rod bearings and piston pins. Outside mics for main/rod bearings, and piston pins. Ring filer. Ring compression tool to insert the piston assembly into the block. Piston top dead center tool. Camshaft degree wheel. Dial indicator and stand with magnetic base. Adjustable length push rods. "Test" valve springs to easily check piston to valve clearance.
Some people use plasti gauge to check main/rod clearances. I never have trusted the stuff.
I'm sure there's more that have slipped my mind.
Keep in mind that building a 500 HP motor doesn't mean the car will be fast. If you can't get the power to the ground you're just going to have another over horse powered slug.
By the way. Is your keyboard broke? The caps lock button seems to be stuck on.
