Trouble with shorty headers
 

I got MAC equal lenghth shorty headers and cant get the passenger side in i removed the smog lines and still cant seem to get them in from the top or bottom anyone have suggestions or installed them before please help!

I got them in , just removed some plugs and for the passenger side the mass air sensor but now the passenger side headers wont line up to the bolt holes it seems likes it hittin something underneath like where the engine mount is but not sure if i should grind it down or just fool wit it some more, there mac shorty equal length headers

Loosen the right side motor mount and jack up the engine a little bit. Don't forget to use a piece of wood between the oil pan and the jack.
