TFS-61617801-C00 1.460″ dual valve springs
TFS-61617802-C00 1.550″ dual valve springs
TFS-6161T783-C00 1.550″ dual valve springs w/ ti retainers
TFS-6161T784-C00 1.560″ dual valve springs w/ ti retainers

I know the 1.560" is intended for a solid roller up to .700" lift, but don't know what the others are spec'd for.


I'm close to ordering and have spoken to both Summit and Trick Flow Tech Lines. Both came back with same selection recommendations based on current engine build, valve train, and intended use provided. Give them a call as they were glad to be of help in making the right choice.

....and thanks for all the advice in the post up up
