You're going to have to go hard with the Ezy-out. You may be able to apply some gentle heat with an oxy to help loosen it a little, and use the ezy-out while its still warm.

Couldn't tell you the thread pitch, but I think they're 8mm.

8mm x 1.25mm

drill a 3 (1/8) pilot hole up the centre of the sheered bolt for the ezyout/auger to get a hold and use a much smaller auger so that you dont have to stress about destroying the threads 8mm x 1.25 is easy to tap cos the pitch is not to steep or too shallow but its hard to redraw when you catch it with the easy out :P

easy out - hard in

Did you say 1500 Single port engine as the inlet stud is a 6 mm.

the later 1600 twin port is a 8 mm stud

Go to the wreckers and get a S/H stud and fit that with some locktite better than jaming a bolt in there.

From memory the stud holes go through into the rocket area so you might be able to un screw the stud from the inside.
