Re: Advice on stripped valve cover bolts
7mm helicoil kit is your best option, you'll always be able to use stock VC bolts and wont have to figure out which ones go where.
The helicoil needs to be installed using red Loctite. It will make for a stronger thread that wont wear out like an aluminum hole after repeated use.
Plus tapping aluminum with a hand tap really makes for shitty threads due to galling and sideloading the tap by hand.
Keep in mind, if there's a dowel pin in any of those holes, you need to make sure that dowel pin will go in flush like original.
Those bolt holes are often stripped because the rubber washers and gasket got too thin, bolt bottomed out and got over tightened.
