Can these be used with a hydraulic roller on an SBC?:



K-850 1.550 diameter double Silicon spring with dampner that is good on flat tappet camshafts with up to .630 valve lift.



135# @ 1.900 - 419# @ 1.250 - coil bind @ 1.160

Will be a street/strip car... probably less than .550 lift and less than 6500 rpm. Looking at an aftermarket EFI setup for induction.

I have only played with mechanical rollers and flat tappet cams in the past, so this is all new to me.
