eight-six Wrote:Out of interested have you noticed depressed areas in the ports just before the valve (seems to be more prominent on the intake side)? Actually what I believe you are talking about is a ridge that is created because the valve seat isn't perfectly centered. The valve seat needs to be ground so the seat and port wall do not have a ridge. When doing streetport work... remember flow direction, some ugly things need more work than others Dan - You can |  .... OR you can ask for help!!!OST Porting service - http://hachiroku.net/forums/showthread.php?t=19991 |
