On the heads that was marked with an "Y" the inlet channel was ported. <br />I came to believe that these were factory ported heads. Other 1937 heads I have had did not have this marking. Is there any work done to the inlet tract on these ones?<br />fredrik@vildabomben.comAnonymousnoreply@blogger.com
