Will 68-70 nova headers fit a 72 chevelle thanx did a search didnt find anything

not on the ones i've seen, #2 cyl tube will hit the engine crossmember... as long as that tube is pushed way back (against #4,6) you might be lucky... look at summit for the pictures (look at hedmans or hooker -not summit or flowtech brand) to see what i mean...

In a word, nope. The steering linkage on a Nova is behind the crossmember as opposed to the front like a Chevelle is.
