These stainless steel exhaust valves are the stock 1.590" diameter as found in the LS3 cylinder heads. They are a great upgrade option for moderately-powered LS engines (like our BUDGET BRAWLER or LSFree build type). These are designed as a drop-in replacement to your stock pieces with better material strength, better machining, and will handle more power.
Sold in a set of 8 pcs.
