If you set them up tight you need to break them in slow. You don't want to seize a piston.

I'm actually around.0035 for clearance seems a little snug to me but I'm being reassured that will be fine
What are your thoughts on breaking in
i was told no overdrive or 5th gear for a period of time

No. I'm pretty sure that little tidbit of information is in the printed instructions that come with then Cometic gasket set. Ask THC about it........

If someone has that I'd really like a copy
