Wildcardracing Posted May 23, 2009 Report Share Posted May 23, 2009 I only use Wiseco. But with all pistons it is a must to make sure the ports/port chamfers are symetrical so the piston is guided back into the ring land evenly so the alignment dowel doesn't get broken off. This is especially crucial on the exhaust port. Quote Link to comment Share on other sites More sharing options...
