So after some thinking and re watching my older videos, we have worked out the valve spring that we had originally installed into the first head rebuild before the bottom end rebuild, were,
Crow Cams 5091-12
Install Height -1.687
Install Pressure- 90
Pressure @ 0.5 lift -270
Max lift 0.542
Spring Rate lb/in - 348
E49 Cam should be matched to,
Crow Cams 7736-12
Install Height -1.687
Install Pressure - 115
Pressure @ 0.5 lift -280
Max lift - 0.537"
Spring Rate lb/in - 364
So they have been ordered and we will see how they go.
