many thanks everyone! i wasn't looking forward to scratching around in junkyards for these.

Got the head back from the shop already. The guy was able to remove the stud without damaging the threads so no helicoil.

They pressure tested it, vacuum tested it and inspected it. they said it's flat, straight and normal!

waiting on the gasket and bolts and exhaust manifold studs from Mitsubishi. should be here on wed ...

thanks again

Pierre
