OK, I have 3 broken exhaust studs on my 2.7 six. All but these three came out easily but these 3 were never going to move! I spray (for several days) with PB blaster, used a torch and nothing worked. Finally I bent one on purpose because I was at my wit's end and eventually broke it. I went ahead and cut the other two off in preparation for drilling. I have drilled out the originally broken one and tried using an "ease-out" but no luck (of course). I'm at the point where I can actually tap the hole for the original thread size. What size tap do I need to buy?

I've used the EZ-outs on other engines, hit or miss results. But will someone explain what EDM is? I've never heard of it. Oh, I did mean to mention that the heads are mounted to the engine, the engine is installed but there are no oil tubes in place. So I have fairly good access, all be it upside down on my back under the engine. Where to get heli-coils or time-certs, what size (stock and one spot larger than stock)?
