me again,

my head gasket it leaking and the clutch isnt all too good, so i decided it would be a good idea to fresh'n up the bottom end a bit along with doing some upgrades.

my question is:
once the Titanium Valve Spring Retainers are installed is there a point to having a reman or a reman cryo treated intermediate shaft installed if the one that already in the block in good shape???

let me know what you all think
