I've installed, set and run in my ph2 cam on my pinto. fitted new rocker arms at the same time and have set the valve clearances to Newman's specs. 0.006 and 0.008. I've now got a pretty lumpy idle and I'm thinking these valve clearances may be too tight. is it worth me running the motor for a week or two and then rechecking, or should I open them up before I put the car into service?
