Cranes profiles date from the earlier valve spring era and do not pushthe envelope
they are smooth- Like Engles the .904 will have more area under the curve- it does not try for maximum lift which would take different springs
Yes that has been my impression.... and, while it is not the topic, I kinda like them for that reason. Less stress on the valvetrain and lower contract pressures on the lifters...... less problems for break-in IMHO. Easy for a moderate build.
BTW, we have not heard from the OP? How is is going?
