That's really cool thanks for the info now that I think of it there is a bag of O rings and other misc. stuff that I did not use when I put the new head on. I guess whatever shop serviced my rig before I bought it must have made a gasket to go there becaude I had to use my roloc plastic air nub tool to remove all the old cruddy gasket material I'll see what Toyota of clovis has to offer me on this O ring thanks for the info.
