Proflow Water Neck, Billet Aluminium Swivel, Silver Anodised, 90 Degree, SB & BB Chev
Proflow's billet thermostat housings not only look good, but they also get rid of leaky paper gaskets thanks to their O-ring seal design.

They're available straight-up or with a 0, 45, or 90 degree angle and come complete with stainless hardware.
