It appeared from your previous post that the intake manifold gaskets were not the problem. Could it be that the manifold bolts were retorqued to the required 18 Ft lbs or more the second time around?

I ask because I am about ready to reinstall my rebuilt SC & new intake gaskets. When I removed the intake bolts & nuts the torque value appeared to be a lot higher than 18 ft lbs, more like as tight as you can get it + 1/2 a turn.

Incidently, my Throttle body had no GASKET installed
