SM Head Modifications on a budget

So far, in my mind, the 2.055 valve with the more “plain Jane” valve job looks the best.

The number two test in the last pic of post 335.

At this point I agree, and there may be an explanation for that. Of the 3 ports, port 3/6 (plain Jane) is the only one that does not have the valve sunk to achieve the steep top cut. The wide, steep top cut is shrouding some of the flow at low and mid lifts on the other 2 ports.

I sure am intrigued by the 2.02 with relocated valves.
