Broken Valve Cover Bolts

Anybody got any ideas on removing snapped off valve cover bolts? 1978 Z1R. Steel bolts into an aluminum head, not the greatest plan as they weld themselves together.

IF you are not joking:

E-Z outs located at any parts store, helps remove broken bolts. First step before drilling and tapping or drilling and helicoiling.

Strange, usually the aluminum threads give up before the bolt breaks....unless the bolt is rusted like the intake boot bolts on one head I have....chris3

I'd put some Kroil on them for a couple days, the the EZ-outs would have an easier job of breaking them loose. Ed
