this weekend I'm going to be helping a friend with his head gasket. we are watching the dvd now and it shows the cams coming out then the head coming off. is it possible to get to the head bolts with the cams still in the head. the head shop specifically asked for the cams to be in the head so they're there for the valve job. just trying to skip putting the head back together to take it to him so he can take it back apart if it's possible to pull it with cams in place.
