Does anyone know or know where to find the following dimensions for the ET39 valve spring:
Free length
Installed height
Seat pressure
Also, is there a "preload" used on the ET39/1 or is it installed without additional shims at the same installed height as the ET39?
I have some "beehive" valve springs from various engines and would like to use them in the engine for my special.
Beehive springs are made to eliminate coil bind when using high lift cams. I am using a set of Terry Prince's MK4 cams and they have a higher lift than the MK2 cams.
