Reply to "Suggestions on 4V Head Rebuild"

Doug, thanks  for the input. I agree with a number of your points. I was hoping I could replace just the exhaust valves, and makes sense to toss the springs.  I had planned on upgrading the rocker arms to something with a roller tip and possible a bearing falcrum and makes sense to go with a 7/16 bolt. I'm surprised they machined the spring seats and didn't put in rocker arm studs.
