Hello, I am building a 455 with E-heads ( first build) A couple of guestions about the heads,first on the E-heads were the heater nipple goes it is threaded.I though they were a press fit. what do you use for the nipple and to plug the other the other 3 corners of the heads. Also in the center of the heads there is a small hole. the intake gasket covers the hole. do you need to plug the hole and if so with what? Thanks for the info. John
