Well i did the H/C/I swap and it runs great but i hear a very loud ticking noise. Because of this i have not driven the car very much. I am trying to decided if this is a leak at the headers or wrongly adjusted pedestal mount rockers. The car runs GREAT. I think i might smell some exhuast in the engine bay but i am not sure. I can hear the ticking at 60 mph, so it is a loud noise. So my question is what can wrongly adjusted rockers do when driving around? Would it do damage to anything. Sorry guys i have been working and have not been able to take off the headers to check for a bad gasket.
