Turbo head build

Yeah I had played with a scrap small block head once a couple of years before I dug into my /6 head. But it was still kinda scary, grinding on a head "for real" that I wasn't wanting to damage.
Which I did plenty of damage to the original seats as cut into the casting from the factory.
In my case the only way I could have run stock valves was to have had all the seats ground out for inserts. That grinder and carbide bits get away from you so easy.
