My home inspection of Speedmaster heads
This is all I'm doing. I used a buffer on a Dremel and removed the burr where the seat was pressed in and smoothed it out with a buffer. That's it. We'll see how these stack up against stock head on a stock 360. Should be interesting when the time comes.... Pictures of one done and the other not. Don't show the burr well on the exhaust side, but the sharp edge is gone.
