I have GT40p heads and have about 1200 miles on my engine. I have 1.6 Motorsport roller rocker arms and I hear a ticking sound coming from the passenger side of the engine. I checked the rocker arms and do not think they are adjustable. How can I tell without pulling the valve cover off again? I do not believe it is an exhaust leak and have tightetned down everything but is there a way to check for sure? I called the yahoo shop that built the engine and they said I would probably need to go with longer pushrods. Don't get me started on these idiots and I can not and will not deal with them anylonger.
