Re: relieving valve pockets

Here is a shot of what I often do around the pockets on the flatties--basically a smoothing of the edges in the direction of the cylinder, and a fairly rough cleanup of the biggest bumps and stalagtites in the ports. Seems to make a nice difference.
About those siamesed ports. If you work through the firing order of the L8, each siamesed port ends up drawing for almost a revolution of the crank followed another revolution before they draw again. Don't know how those carbs would react to that irregular pulsation.
We need a carb wizard to bring some wisdom here
