1968 BARRACUDA - 440 Water pump housing

Your high pressure hose is nice and everything but the cooling circuit of a torqueflite runs at around 20psi. Maybe less. Taking the chrome off that waterneck use 180/220 grit on a flat surface. Give that gasket something to grab. Is that gasket the thick one with the plastic beads for sealing? Dont care for it myself. Stock gasket is fine as long as the surfaces are flat.
