Does anyone happen to know the exact specs of the threaded part of the valve cover bolt?
Thanks!

Not sure, but one method is for you to pull out your tap and die set, grab the gauge in there and that should give you at least the TPI. Then test fit some of your dies until you get the correct diameter. It’ll be the metric kit.
