Before I forget , vnemous wants to see the "the show" at Gilligan's Island this summer .. :eek: ;) :D
Yes that is true . If they were going to worry about one side being exactly like the other , that would be the place to do it .
As you move farther way from the base of the block , the size , shape , square inch's or exact volume changes . So 1 3/4" might get you closer , your still trying to correct the primary length by changing the collector .. :nonod:
But then , if you consider that the primary length mismatch is worse than these POS headers . Well it would be like FMP winning the Special Olympics , even if he won , he (and these) would still be ******** ... ;)
