Need advice comparing springs I am trying to find a substitution for my 918s that are giving me valve float. I was recommended the new 26986 beehives. They are supposed to be the beehive version of the daul 986 springs I compared these springs on comp cams website and the 986 springs are supposed to be good to .650" but both the seat pressure and the open pressure are lower than the 918s. Is this really a better spring?? Here's how they compare.....
26918 26986
130# @ 1.800" seat pressure 123# @ 1.750
318# @ 1.200" open pressure 284# @ 1.175
1.140" coil bind 1.040"
313 rate (lbs/in) 280
130# @ 1.800" seat pressure 123# @ 1.750
318# @ 1.200" open pressure 284# @ 1.175
1.140" coil bind 1.040"
313 rate (lbs/in) 280
