you can buy just an inner spring from comp cams #974-16 making a double with enough tension for a flat tappet or hyd roller





Would you recommend doing that for a comp XS290S or will the stock Stealth springs handle that cam?


I have a set of the first non CNC batch, the springs on them had 140 lbs pressure on the seat and 340 lbs at 600 lift, coil bind at around .700, if I remeber correctly. so I would say they will work fine with that cam and even 1.6 rockers I would probally shim the springs up so they had about .080 from coil bind on all sixteen springs and replace the retainers and valve locks with some super sevens or ten degree lock and retainers that would fit that spring properly I haven't use them on a motor yet but I will shortly, maybe after having them done by Jeff if I can get a deal before this winter
