Slant six builders...Lets talk Cams

Here's a picture with a 1.550" diameter dual spring in the slant six's stock, unmodified spring pocket. There's actually a tic more room. Might go to 1.580 but Idon't have any of those. lol Course, to use the dual springs, you'd have to mill the inner step flat, but that's a 15 minute job with the right tool.
