factory lt1 springs
ok im looking for some after market springs to go with the scorpion lifters i've selected to use with my mostly stock lt1.. i know i'll also need a tune im just having a hard time finding some really good valve springs to go with these rocker arms.
Scorpion Performance SCP1036BL - Scorpion Narrow Body Self-Aligning Rocker Arms - Overview - SummitRacing.com
anyone know some good valve springs other than lt4 springs that would go well with these and the rest of the stock drivetrain?

Re: factory lt1 springs
The factory springs aren't that good for stock cam and stock 1.5 rockers so who cares what the specs on them are.
With 1.6 rockers and a stock cam LT4 springs are a good way to go, think they are a whole $35 a set.
If you think more serious heads/c am upgrades are in the future I would at least consider 7/16" studs/rockers and guideplates now then what you have will grow with you instead of replacing it all as you mod further.
You do not buy overkill springs to match a later setup because in a performance application springs should be considered a wear item once you get into aggressive aftermarket cams.
