which are good valve springs for a budget. i'm not really looking to upgrade to titanium retainers.

is there and advantage of single to double springs?

here are my choices i think:

26918 Comp Cams 26918 Conical Spring (LS1 replacement) Suitable to .600 lift with more aggressive ramp-rate cams (Works with stock or Comp 772-16 Titanium Retainers) $159.99

144832 Crane Cams 144832 Dual Valve Spring Set, 1.275 Diameter LS1 Replacement springs suitable to .650 lift and with more aggressive ramp-rate cams (Works with Crane 144661 Titanium Retainers) $149.99
since it says "works with" does that mean they are required?

and why are new seals needed with the Crane 144832s??

i'm looking to do a vavle spring swap, and possibly a 1.8 rocker inistall later...and then a cam after that (i know Comp makes cams compatable with the rockers)

 

if youre still runnin stock cam with 1.6 rockers at the most i suggest the LT4 springs....theyre 26 bucks from GMPD iirc and they handle to .525 lift...part # 12551483

 

Check out Combination Motorsports line of XE Components springs. I do believe they're somewhat cheap, but work good.

i would but i plan to do rockers and/or cam in the near future...don't want to do the work twice. and springs for $150 isn't bad...specially if i know they will handle a decent cam
