Re: mac headers install I dropped mine in from the top. It took a little wigglin but they went in. The valvecovers were off which makes it a little easier. Most people say they can go in from the top with just the coilpacks off. Removing the coilpacks is a bit of a pain but if you have the patience its not a prob.

Re: mac headers install Folks have had pretty much equal success either way.
Personally, I'd prefer to install them from the bottom, if you can get the car high enough in the air to do so.
They will slip in fairly easily from the top, but you'll have to remove a few things to help out (mainly the valvecovers).
When I originally installed MAC headers on my car back in '99 (one of the first mods I did), I did them from the bottom, and had to unbolt the motor mounts and jack the engine up a tad to have enough room, but you may get away without having to do that.

Re: mac headers install When I installed the mac headers on my car I did it through the bottom. The driver side was a breeze, but the passanger side was a bit tougher I had to jack the passanger side of the engine without removing the mount and slide it thru the oil pan. I removed the spark plug to prevent breaking them and replaced them with tr6's. just take your time I managed to installed them on lift with a buddy with power tools in less than 3.5 hrs.
GOOD LUCK

Re: mac headers install Thanks for all the info I guess I'll just start pulling the old stuff off first then see which way I'm going to install if it looks good.

Re: mac headers install Valve covers off and in from the top. You just have to find the right way to turn the header as you drop it in and it will be a breeze. No motor jacking, no starter removal.I had them in within 3 1/2 hrs. The Y pipe etc. took another 2 hrs. Total job= 5 1/2 hrs beginning to end. I just pulled them out 2 days ago for my motor swap and they came out the top as easy as they went in.
