If you had your firing order wrong, you would have some cold cylinders and thus some corresponding cold header pipes. Run it and spray some water on each header pipe with a squirt bottle. The pipes that don't sizzle would be your dead cylinders (don't ask me how I know this... ). Edit: Did you swap cams for some reason ? That's where we ran into trouble - different firing order for HO / non-HO.
