redynscire Posted July 2, 2011 Report Share Posted July 2, 2011 how common are cracked heads on a l67, say between all the valves? i got some fat cracks "gaps" in a couple. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted July 2, 2011 Report Share Posted July 2, 2011 overheated iron heads will do that. aluminum will as well, but generally would warp before cracking between the valve seats. Quote Link to comment Share on other sites More sharing options...
