This sale is for one set of 8 valves.
PS824 forged high temp stainless. Hardened keeper groove.
NON MAGNETIC PBM/ERSON Race series stainless steel valves, swirl finished, 1 pc. undercut. Non magnetic is very important. Our cost on these valves is more than double the price of most low cost valves on the market. We know for a fact that many head builders use the low cost magnetic valves. We do not use them and never will. If the valves pull a magnet, they are not high temp stainless. They may be stainless, but they have very low nickel content in them. Stick a magnet to your stainless kitchen utensils; they will pull a magnet very strongly. Kitchen utensils are made from 400 series stainless, and have very little nickel in them as they don't encounter extreme temp ranges. It is the higher nickel content that allows a valve to withstand high temperatures.
These valves are swirl finished, undercut style, and have a very well designed lock groove. As with all of our valve train components, they must meet our specs or we will not sell them. When comparing prices, be sure that the valves you're comparing these to are non magnetic. Low temp valves will fail with ease under the right conditions. High temp valves are not just for those running to extremes, they are essential for all carbureted engines.
