poor fitting 2055's

Not sure if I got a bogus set or not , but the flange openings are crowding the head opening. All the port corners on the flange are too small by about .100
If I put the die grinder to them I'll probably hit daylight.

Is this the exception or the norm?

I've been trying to tell everyone about that for years, but all seem to think it is alright.

Well I don't, so I do grind them out some.

They use 1 5/8 flanges but shrink the tube down to
1 1/2" when they install them.

Mighty poor to my way of thinking.

And the Y pipe is a poor fitting piece of crap as well, header to header. Looks good sitting on the floor though
