It is not normal pressure on idle i think? normal is near 28-30kpa?

It depends from cam. Narrow cams with zero overlap gives lowest absolute pressure. With overlap increase pressure rises. In some cases it can be in 90...100kpa range.

50 is perfectly normal for a stock M20. It will loose some from the lower c/r.
