a 3 angle valve job has a 30,45,60 degrees cuts. The valve of 44 degrees still seats in the 45 angle cut. The valve job helps with airflow. There is less disturbence with the 3 angle cut. Thats my take on the matter. Some poeple might get theres cut to a 30 angle but i don't know.

here's an example
This is a really good arcticle with before and after flow numbers on an old big block Dodge smog head. This used to be a common mod with Harley engines too. The results are very impressive.
