here is a pic of them on my car,if you look behind the blower you can see them

 

some headers you have to loosen a motor mount, or actually lift the motor up, or disconnect the steering linkage to drop them in.
also, when you get them set in place, get all the bolts started before you torque them down..............if it was easy everyone would do it

 

lol ill just stick with equal length shorties then.

 

would drilling the bolt holes a little bigger work? because i dont have a engine lift

 

you don't need a engine lift.
I would not drill the holes out any larger Wes,start at the back cylinders and work your way forward using a pry bar to move the tubes around a little until you get the bolts started.
Do not tighten any bolts down until you get them all started,then tighten them down

BTW---He is putting on unequal length shorties
