Something similar happened to me. Decided to keep the old exhaust valves on a rebuild. As penny-wise and dollar foolish proved about 100 miles after, heard a little ping, then a bunch of engine ratteling after comming out of a street corner. Destroyed head, piston(s), metal contamination, etc. All for trying to save a few bucks! <img src="/forums/images/graemlins/scared.gif" alt="" />
