intake gasket instalation question

I tried doing some searches but couldn't answer my question. I'm rebuilding a 1990 350, all done except for putting the intake manifold on so heres the question. The gasket is supposed to have 2 of the coolent passages blocked off with little plate things. I need to know which passages are supposed to be blocked off. Thanks for any help.

Okay never mind I found one of the old gaskets and was able to line it so that i know that the block off's go in the back passages.

it usually doesn't matter, since the intake itself blocks those passages.
