Valve float with roller rockers

[SloGN]

The reason I asked is that 1.750 is the standadr for the GN1 head and according to my comp spring sheet the 980 spring is 92lbs @ 1.700 so at 1.750 that would put it close to 77 LBS on the seat. A comp 941, or behive will fix you right up if you use a beehive you need special spring seats (we have them) pull a spring, get a height mic and check the nstalled height then double check your springs and let us know what you find

Thanks mike.

Thats my next step is to pull them off and measure. I didn't double check my machine shop but he has always done what i asked him to do. but you never know.
