springs for xe262h with rhs pro actions

[markw]

hi, are the springs 972 ok for this combo? the cam sheet suggests 942 (i also have these) but the RHS heads sheet recommend 972.

the 972 are a taller spring (about 2.208 as opposed to 2.1 for 942) diameters are all different etc, so im assuming 942 wouldnt fit anyway, but the 972 is rated 308 and the 942 is 339 not too clear on the whole springs thing yet.

cheers,

Mark

To answer your question either spring will work for the cam but the 972-16 spring is the better choice and will fit with the heads better so it is the one I would use.
