I had to pull my C90e heads to get threaded rocker studs put in because the stock ones started letting go. Reinstalled the heads and put the engine back together but now the engine turns over and doesn't run. I've confirmed the firing order and wiring is correct and I never moved the distributer through the process. I pulled the spark plug on cylinder #1 and just a brief run through revealed no compression so I'm thinking the valves aren't set right. The rocker arms are Comp Cams self adjusting retrofits and are put down with Comp Cam polylocks. All the material I consulted said they were self adjusting and just torque to factory specs. I never turned over the cam till the engine was put back together so it made sense to me. Do I have to follow the three step 0 lash setup on them? Any help would be appreciated. Thanks!
