Do I need gasket sealant for this application?? I could not tell because everything got soaked in coolant. The guy at the shop said I should get it and sold me a tube, but I thought I would get some feedback before I started.

Any hints??

I would use some RTV sealant since you are mating a water jacket (TB water cooling) to a part that has engine vacuum.
