I quit using washers when I went to .25 caliber. I was after max power with less deviation, so I went the “adjust the tophat” route with the .25.
On my valve, I can turn the tophat all the way down to 0.0″ gap. Must have a lot more threads than most. I ended up right around 0.65″, seems to work well with a stock valve.
