They flow equally to a 346 0r a set of 906s. If you were to run a dyno test with all 3 you would hardly see any difference.
Yes the templates will work on all 5 BB heads except for the Max Wedge heads. . I did a set with oversize valves,very mild pocket porting and a gasket match. That made a world of difference.
Just start grinding to match the templates. They are marked for the amount of material to revove IIRC.

see if you can find Dulcichs' Mopar Muscle porting articles. Google it. Good info. You trim them on the outside edge of the black lines if using 2.08/1.74 valves. if using 2.14/1.81 you'd cut them out then use them in the leftover plastic to cut new ones that are wider by .060" (.030" on each side) for instance on the intakes (2.14-2.08=.060"
