Pro Comp intake coolant crossover
 

The coolant crossover is the only solution i can find for the four holes being on each of the corners of this intake manifold I just purchessed. I am doing the vortec head swap and this is the manifold I plan on going with. Did I make a mistake when buying this?

Can I just plug three of these holes and use the other for the temp sending unit?

And what about the oil pressure sending unit, is it in the manifold or the block? Because I do not see a place to put the unit.
Thanks!

There is also a tapped hole that goes into the port, between the intake and the dist. hole. Whats that for?

Vacuum source.

On mine I plugged the rears and I believe my vacuum "tree" went in behind the carb flange.
Fronts, whatever you want. I believe I plugged one and used the other for a temp sender

Sending unit is behind the intake, on the block.
