What sizes for carb setup?

I have searched and found no solid "i am using this, and it works" so here we go:

I have a 2.7 stock p&c, sc cams, headers.

I am putting on weber 40IDA3C's and need to know what sizes for
Venturi-
Main jets-
idle jets-
air correction-
emuls tubes-

Please lets not debate on why

I think what Steve said. I am about to go down and replace my 60's with 57 idles. Everything else as Steve detailed. Same engine as you, except mystery cams and 34 venturis.
