Easy is relative but mine installed easy. That being said, the last headers I worked with were on a 428CJ big block Mercury Cyclone with power steering. Those were hard....very hard to install.

Anyway, the trick to the Tri-Y headers on my car was to hang the header on the two outside bolts just barely threaded in so the gasket is in place. This will allow you to move the header in and out. I then slid the number 5 bolt through the flange and gasket and used it to snug the header down and position it. I then was able to put the rest of the bolts in very easily. Most with a socket and extension from below. Same deal with the other side. I don't think you will get any D-Port header in by snugging the header to the block then trying to get the bolt behind the center ports in. That bolt needs to be angled in to the flange, allowed to move and the first bolt to get snugged.

I had no need to make a custom wrench, grind anything or use any funky bolts. I did not need to jack up the motor. I did have to remove the starter and oil filter housing but I would expect to have to remove both with any Pontiac header. As Ron quoted me before. I don't expect any header to leap out of the box and onto the car. but these headers are about the closest I have found to doing exactly that.

Ron has made some changes since my headers were built. None of them look like they would make installation more difficult so I would think your experience will be much the same.
