I am building a L28 race motor. I ordered Nissan Motorsports stainless race valves in early Jan. Have received 3 intake (1.73") and 3 exhaust (1.38"), and three someother that were supposed to be intakes (1.42"), so may still get the intakes, the exhaust however are back ordered to Japan as they are out of stock at Motorsports. I have called local Nissan dealers and Courtesy Nissan in Dallas hoping to find some left on a shelf somewhere, no luck. Any ideas of other likely sources.
