I was wondering if you can replace the little wire clip that goes on the intake rockers( I think it's intake) without pulling the head? When I had my head worked one of the clips broke and I was told by the builder that it wasnt needed. I believe this clip missing is the source of my small ticking noise in my engine. I checked the valve adj twice so I'm pretty sure it's not a valve adjustment issue. It's really not bad but it just gets on my nerves. Thanks.
