Well, I have the Helms and have looked through the procedure. Seems pretty cut and dry, I just haven't ever done any in-depth engin work like this. I do the work on my car.... just not like this. So, follow the Helms, use hand tools, and bring the head to a machine shop.
Also, what is a 3-angle valve job? I don't want to look like an idiot, or get taken for a ride at the machine shop.
Thanks.
