exhaust header question

I just bought a header to replace the cracked origional one.   The pipe
protrudes about 0.060" past the flange,  the old cast iron exhaust was
flush.  I am wonder ing if this is going to cause a leak.   Can those of you
who have headers tell me if yours protruded  or were they flush?   I need to
know if I should send it back?
