Trying to get all the bits ordered for a fast 92 install on my trans am. I will be getting a nick willams 92mm throttle body to go with it and utilizing the factory fuel rails. I know the fast doesn't come with gaskets or hardware so I'll be sure to order those with it. Where I'm getting hung up is with the coolant crossover tube. Will a 4 corner steam kit from Earls performance take care of that and fit with the fast or will I have to plug the rear and put a crossover tube on the front?

If you want a four corner steam vent kit, you have to get one that is specifically made to work around a FAST manifold.

Here's a kit that is known to work.

I plugged the rears and done the crossover on the front. Simply cut the tube where it mounts to heads and weld/braze it shut as rear plugs.

see attached: rears are hard to see in photo but you get the idea.

Thanks for the replies I'd rather not plug the back so I guess I'll be going with a 4 corner setup . Trying to order all these parts from one place so I guess i will be going with the motion raceworks 4 corner kit for low profile intakes .
