Eibach 20701.212 valve spring height

[reclino]

What free height do I specify for these springs in rebuilt 930 heads with fresh SC cams? These are stock equivalent springs, I am building a stock 930 engine, except for the cams.
The old Eibach catalog I have says seat pressure 55 lbs @ 36.5mm,. 183 lbs at 25.5mm, coil bind at 20.5mm
I assume this means my install height is 36.5mm.
