LSM valve springs anyone got any info?
i recently got a set of lsm valve springs and titanium retainers. the springs are used and i plan on having them checked before i install them. they are tripple springs part # L700A. specs are .635" I.D., 1.680" O.D., installed 385# @ 2.100, open 1050# @ 1.200, bind 1.140". i'm not sure about spring specs so could anyone help me out as to what kind of max lift these are good for? do i need different spring seats with these springs or will the stockers work? until now i have never heard of lsm before, just wondering if anyone has any input on these spings. is anyone out there using them and what do they think?

Looks like they are designed to run 900 lift solid roller. Some aftermarket heads can take that spring, but only a few. A stock head could be made to handle these springs with longer valves, spring shims and a custom rocker system.

so i take it these springs are a little over kill for my set up and won't work without major modification? i'm gonna be running ported 806 heads with a t-rex cam and hydraulic lifters.
