I have Throttle Body Coolant blocked at Injector Housings and do not use anything on 1/32 Plenum Gaskets.
Set Plenum in Place making ALL electrical and vacuum connections and then slide gaskets in place (lift Plenum just enough to slide gaskets in place).
I tighten Plenum SS Allen Head Bolts tight but not too tight and then check them once in a while (less than what book calls for as I have no coolant to TB)
