Did you end up drilling them all out or did you surrender to a machine shop?
It was terrible and in hind sight made no sense to tackle on my own.. Forget about the time and frustration but after 6 hours and 4 trips to different stores to buy more bits, I probably spent double what a shop would've charged.. They're done now at least and so far all looks good..

I got the heads locally off craigslist freshly rebuilt.. Changing the plugs out is on my ever-growing list of to-dos for this fall/winter when I'm not so rushed..
