    Default TFS-15410-24 Valve springs. A few ?s

    Hi,

    What can you tell me about TFS-15410-24valve springs? I'm in the process of having 3v heads ported and looking at options for springs. I'm a novice at matching springs to the valvetrain and would like a more informed opinion. My current cams are at .530 lift but I may go to something bigger with the ported heads and would like to have capable springs in place.

    Thanks

    Those springs are good up to .550 lift and can be used with O.E. locks, retainers and seals. They have 105 lb seat pressure installed at 1.670" and 270 lbs. open pressure at 1.120" with a 300 lbs. per inch rate. They bind at 1.060".
