Rev Kit springs

Post  JBR-3 on August 11th 2013, 5:13 pm

I'm not aware of any available rev kits for any Ford, but I'm curious about
the specs for a rev kit spring, likely for a Chev application.
I.E., what would be spring rate and installed height ?
 
On engines that use a rev kit, are the valve springs then somewhat
reduced in pressure ?
 
Considering possibly fabbing up a deal for the BBF.

The CompCams springs for a small block Chevy rev kit are inner valve springs #974, (the pale blue ones)..  They have 96 lb/in of rate, about 40/45 pounds @1.500" installed.
