valve springs

X2 on the Isky Tool Room, on there fresh I'm upgrading to the RAD treated version. Did 11,000 mile, two seasons on the last ones. 230 on the seat, 750 open. This time 250/820. Net lift is now .860 is the reason for the change.

Pac springs here... I have broke K-Motion springs also(if I
recall correctly) they were either K-900 or K-1000
