gn-1 installed valve spring height?

A friend of mine is looking for the installed height of the springs on the gn-1 14 bolt heads as they come shipped from champion usually.


thanks

1.75 here too, 8 bolt though...

Correction, 1.725. Older version 8 bolts...

Id call them because they could possibly use different springs in different applications. If they used a double spring for a solid roller with .600+ lift id bet the installed height would be higher than the above mentioned heights.

Mine are for 14 bolt new version aluminum heads gn-1s with a roller cam.

Solid or hydraulic? If they use the stock diameter spring then chances are anything around 1.700 is correct. You need to go by the spring manufacturers specs. Not the type of head being used.
