No words, just four letters: TSRM. Toyota Supra Repair Manual. Read it, refer to it, and if you have an iPhone, bookmark the URL on your home screen. Android device, there's an app in the marketplace for it. INFINITELY more useful than asking for advice in your own build thread. Every nut, bolt, fastener and electrical connection is covered. It's the only book a Toyota mechanic will open when working on your car at the dealership.
That said, the 7M isn't an interference motor; ie, the valves don't occupy the same space as the pistons will at top dead center. Therefore, you can't damage the valves with a bad job like some other motors, however, following the procedure in the manual will get it right every time.
