Alright so I have a ported and polished stock Silverado throttle body to throw on my new to me SSS and I noticed that there are those 2 spouts on the bottom of the trottle body that have hoses that run into the radiator so when I swap them does that mean I have to drain the coolant from the radiator? Might be a dumb question but I figured id ask, also is there a gastket between the throttle body and intake manifold that I should replace when I swap them? Like I said possibly a dumb question but I figured Id ask!
