<div><span style="color: rgb(38, 40, 42);">As a result of my broken timing chain, all but one of the valves are bent. Since I still race SCCA, I need stock diameter (head diameter) valves. The stock diameter valves do not have the stems necked down for better flow. When i built this head years ago I bought the oversized valves with necked down stems and ground them down to stock diameter. </span><br></div></div><div id="ydp7377a1d0yahoo_quoted_7435424244" class="ydp7377a1d0yahoo_quoted"><div style="font-family:'Helvetica Neue', Helvetica, Arial, sans-serif;font-size:13px;color:#26282a;"><div><div id="ydp7377a1d0yiv1533410920"><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;" class="ydp7377a1d0yiv1533410920yahoo-style-wrap"><div dir="ltr"><br></div><div dir="ltr">My question for this esteemed group is - Does someone make or sell stock diameter valves with 5/15 inch stems that are necked down for better flow?
