Speedmaster 190 Data

Installed height is advertised at 1.9, these measured at 1.875. I got the set with springs for flat tappet cams. They measured #[email protected] and #[email protected]. Guide fit was good and no assembly issues. I've measured two chambers on one head and got 66cc one one and 67cc on the other. My methods are not lab quality, so that 1cc difference could be me.
