eyevahn When I disassembled each valve I placed them in an organizer and labeled them, so I know they are correct. The only thing I can think is that I completely forgot about the washers that sit under the springs when I took the head to the machine shop. When I got it back he had placed the washers in a zip lock for me. So they were not placed back into the same spots as they were taken from. But again, the intakes were not thrown off so I don't know...As far as the clearance measurement goes, I guess I'm still a little confused. I thought I could, with the head sitting on my work bench, torque the cams down to spec and then manually crank them with a wrench so that the lobes were pointed exactly away from the lifters to get the best measurement. So, is that not the case? How would having the head in the car with the chain attached change the clearance?
