The geometry is pretty bad though. The installed height is not quite 2” so the .650-.660 roller will work.
If I had a height closer to 1.70 and a cam around .550 wouldn’t need it.
Mike from B3 racing did a nice job with that kit. Engine should have a smooth valvetrain at 7-8 thousand rpm once I get it lined out.
Here is a old pic I sent Mike. The rocker was eating the spring, until that kit moved it up and away. Otherwise you have to mill the stands off, and install stands or blocks.
