Nope
Proportioning valve fitted to that car
So all 4 6 8 and drum or disc front all used the same cylinders (3/4")

L34 was the only one to use the 7/8 wheel cylinders due to them using the HQ 10" drum system

You would then need to change your shoes too... as the HK cylinder is the same as the LC-J one and runs flat button pistons
Whereas the LH-UC runs cylinders that use pushrods coming out of the pistons that sit on the shoe differently
