My ~11:1 stock bottom end setups like TR55s, but my 12.2:1 383 liked TR6s. Here's some good articles that will help you determine heat range and everything else too.

Well considering you bought Brett's old motor you need a gasket style plug. I would start out with some AR3923's on that, maybe even a 3924.
Start cold and work you way up, dont start hot and work cold you will end up hurting things.
AFR heads require gasket plugs, just like LS1 motors.
