excellent product. seals dry and very easy to remove. we ARE all removing these covers ever year to inspect those floating rocker shafts, right? They have a bad habit of floating into contact with the covers and rubbing a nice circular hole. So get these and pull the covers every annual. easy peasy. These are a little more firm than the red ones and snug down better, I think.

Very poor quality control. Piece cut out of one gasket. When replacement requested shipped wrong products. Makes me wonder if manufacturers (Gee-Bee) is operating on all cylinders.
