hell that machine shop is closed down now but i was always doing the little stuff like that, i believe its what sets apart quality and just getting it done ya know? most shops either dont pat attention to bolt holes or they simply brush them, we tapped every hole in every head to make sure everything was right. of course we'd catch more partially damaged holes by really paying attention to stuff which equals more money for us by charging for heli-coils.

i'd always make sure the 45 deg cut on the seats was towards the ouside of the valve instead of the center too, opening things up a lil bit, and if the heads were old and had umbrella i would machine them down and put positive style seals on. (with the right tool, you can machine guides down with a common 3/8's drill and to do both heads it would take like 2 minutes

heres the tool, hell prolly worth buying, i could "rent" it to these people on here wanting to work their heads LOL
