i use plumbers tape on sending unit,i do not goop carb to gasket i like permatex for everything else

(1) Seal valve covers to heads - Permatex Ultra Black  RTV Gasket Maker to hold gasket to the valve cover in a few spots, nothing on the head side.

(2) Seal intake to block/heads - Permatex Ultra Black  RTV Gasket Maker to hold gasket to head in a couple spots, and in the corners where gasket meets rubber gasket on the ends.  Nothing on the intake side.

(3) Seal carb to intake - gasket only.

(4) To put on the threads of intake temp. sending unit etc. - white teflon tape.  I've tried to use pipe dope, but it was a bit messy, and didn't look near as good as teflon tape.   Make sure to use enough tape to go around the male end twice, and wrap it the right way so when you screw the male end in it doesn't start to unwrap.

Hi,

Just wondering in your opinion are the best gasket/thread goo/s to use to:

(1) Seal valve covers to heads
      Very light bead of GM contact cement.

(2) Seal intake to block/heads
      Throw away the end gaskets, use silicone. Gasket, just enough contact cement to hold it in place  to install.


(3) Seal carb to intake
      Dry

(4) To put on the threads of intake temp. sending unit etc.
      Tiny amount of pipe sealant. Some say teflon tape insulates it, defeating the purpose of the sender.
