Broken exhaust bolts
Just got a very good deal on a set of 243 heads off of a truck. the bolts are broken off in the 2 end exhaust holes on both heads (total of 4). What's the best way to deal with this, Helicoil? Or can they be drilled out and removed? The guy gave me the valley cover (along with rockers, stands, and pushrods). Noticed it has the PCV setup like the LS6 cover but no spots for knock sensors. Is this usable?

I have a set of 317 heads that had 2 exhaust bolts broken off. One was sticking out far enough to get some channel-locks on it and back it out. The other one, I drilled and used an E-Z Out.
