I have about 1000 mi. on new Edel Alum heads and I have the valve covers off to adjust the valves (one is ticking). Should I retorque the heads for good preventive measure?
Yes, you should if not already re-torqued. I'm installing the Edelbrock heads/cam package now and the assembly tips state "A head bolt re-torque is recommended after initial start-up and cool-down (allow 2-3 hours for adequate cooling)."
