35-45-60-70 Blend 70 up to 60 Good for concave chambers like conventional BBC heads. 18 to 26 degree heads, Dart, Brodix ect ect.
40-45-62-72.5 Blend 72.5 up to 62. Works good for chambers that are concave like 15 degree heads.
After the blending, those become 3 angle valve jobs.
Yep.

With the victor, it’s worse than the LS head. You have to transition from the seat angle to the basically zero degree chamber. The only way you’re going to be able to gain any length on the top angle is sink to the valves. And...... the steeper you make the top angle........ the more you need to sink the valve, if you want that length.
