Cam advice for more torque from 340

OK, I will have everything I need today to start putting this thing back together. I will reference the FSM for the proper torque numbers.

For the timing cover and water pump, any special treatment on the gaskets I should use? I have a new gasket set, I cleaned the matting surfaces up. Should I use any RTV type substance on the timing/pump cover? Looks like it had it on there before.

Any other tips for putting in a new cam, installing a new timing chain, reinstalling the heads, oil pan and timing cover?
