Do I need coolant crossover pipe ?

Doing a 402 alum. block buildup. AFR heads slp shortblock. fast 90/90 . The fast T-body doesnt have a tube on bottom for the coolant line frome the crossover pipe. Can there be plugs installed in the front coolant holes as in the rear ones ? or does this pipe need to be in place and block off the tube coming off pipe ?
Thanks

Is that where it normally hooks up too ? It's been a few months since I pulled the motor and it looked like it went to the throttle body. I just forgot if thats the case .

Can you guys post pics of what you're talking about? I have a LS1, but I know for the longest time I haven't had any line going through my throttle body. I just hooked mine together rather than going on both sides of the throttle body.

You do not need to run coolant through the TB. Just run from the vent line to the radiator or you can run from the vent line into the top of the water pump (which makes for a very clean look)

Here's my deal.. of course I went way overboard.. lol
