The 200's won't be a problem labor wise, I may need help locating some of the smaller stuff like valve stem seals, & valves, but with all the info, make model, etc, we should be able to find everything we need. Time may be a little longer on the first of any head, as, if I need to mill the surface, I may have to fabricate the appropriate fixtures to hold it down etc. No charge for any of that, I just add any fixture or tool I fab up, to my collection for future jobs.
Like I said, it's just something to stay busy with...
