Does anyone know? It doesn't match up in MM or Sae. Have a couple holes stripped out and looking to get a heli coil kit to fit it. Thanks

They make this liquid steel stuff. It's an epoxy that they say you can drill and tap. I wouldn't trust it to hold anything strong, but valve cover bolts, fuel bowl bolts....stuff like that it should be strong enough.

They are 12/24, willeys has Helicoil kits for $35.

Holley also has a kit to repair these. Don't leave home without it!
