Need some help. I have a 68 200CI I6 that the exhaust manifold is warped on. I took the head off and found that the second port back from the front has a bolt broken off. And to make it worse someone at one time or another tried to drill it out and got the drill walking side ways. I have a couple of good 170 heads that I could put on the engine. My questions are: Would I be better with the 69 head (the one with broken bolt, on the 68 engine ) or would a 62/63 170 head be the same. I should be able to drill through and maybe put a nut on the back side. Any suggestions on how to start the drill in the screwed up hole. Any other suggestions on what I might try? thanks,

Neil

The local machine shop should be able to remove the bolt and if needed put an insert into it and clean it right up. If your not sure of a place just ask around at parts stores, theres always one or two places in town that all the stuff gets sent to.

I agree, usually the machine shop is your best and most painless way to go.
Just be careful though as I once took an I-6 manifold in to have it milled and got it back with a mounting ear broke off,and of course "It musta' been like that when you brought it in sir."
Yeah I always take in useless parts to be machined.
