i have used copper spray for years...it does not clog and I never had an issue with it. I use it on almost every gasket especially the valve cover gasket. everyone has their special way. yes you can back the nuts off to retorqued, i am pretty sure arp is made to be reusable.

check your check valves ... left paper towels ... spark plug center gaskets
