Product description
Using the original design of Model A valves and guides, these valve sets have been re-engineered and fully upgraded to deliver optimum performance. They provide lower wear characteristics and greater extended life compared to anything else on the market! This is a result of modifying some of the stock dimensions on the valve head and 45 degree face, as well as tightening up the tolerances on both valve and guide. The valve sets also have a modified valve stem length to compensate for decked blocks and different grinds of camshafts. The result is an increase in compression and improved valve sealing under all conditions.
