Default Stripped stud

I finally stripped a head stud. I'm assuming this can be fixed with a 3/8-16 helicoil.

Heli-Coil or a Timesert ... Time sert is a bit easier t use but a little more pricey

No Timesert for me...I use threaded inserts from Fastenall...thin wall (close tolerance) usually...and No Odd Size tooling required!!!
Edit; Tho a helicoil would be just fine in this application!!! And... those are 5/16 fasteners!!

I had a time sert put in to the exhaust pipe hole in the read head because the original hole got wallered out. It looks real good. Thanks.

Time-serts were invented about 5 minutes after the aluminum head was introduced!

This is why I changed from bolts to studs.

Stock Harley heads, and S&S heads use different thread sizes. 😉
