No.....
If you just changed valve-bodies, the diameter of it might be a little smaller!!

Since the valve-body locating screw and transfer port are next to each other...
I personally put a small drop of blue loctite!!
It acts like a thread sealant!
Don't any stronger thread locker... Then will have to use heat to get it Off!!!!!!!

Good Luck,
Stuart
