To add to what mark wrote.....which by the way is "Compression ratio".......
"Squish" in a Corvair head with the STEP in it...as do most engines versus an "open Chamber" [ in our case Smog heads with domed pistons and some early low hp engines ]
Is the distance between the "step" and the top of the piston....... factory is usually approx. 0.080"
By decreasing this to approx 0.040" you get less pinging......yet have higher compression! win win!
