I have made the block and head surfaces flat again (still some clean up to-do, I will post some pics soon)

I am now wondering about the head gasket, do you guys use the red rtv stuff to seal it? I saw a kit that sells it with it, I just bought the kit with all the new TTY bolts, gaskets and little rubber seals, but no rtv. Do I need that? Is it part of the manufacturer spec or not?

Thanks again!
