Are the main seal upgrade kits worth the trouble/expense?
In my opinion yes but the housings sometimes need a bit of fitting,
depending on how much the crank center has been changed due to line-boring.
My reply wasn't very clear so let me add that that isn't so much the crank
center being changed that affects the fitting of it, it's mainly that when the
housing bore is redone it closes up the housing bore into which the seal
housing registers. It makes it slightly elliptical & the OD of the seal
housing
is essentially too big to fit properly. They usually need some metal removal
in order to get them concentric with the shaft & a good fit in the housing
bore.
