I am running 105lb valve springs to suit my L67 Stage 2 COMP Cam will that be ok?

We would recommend running 130lb valve springs with our Stage 2 COMP Cam and 1.7:1 ratio rockers. While you could run 105lb springs with that cam, the fatigue life of the valve springs would be compromised leading to them prematurely failing (breaking) If you have any other questions please do not hesitate to ask.
