I am getting close to putting the motor in the shit box. If every thing goes well it should be in monday. The heat exchangers will not be ready till next week.

Is it easy enough to put the HE's on later or should I wait?

i think its easier to put the HE's on last, that is after the engine and everything is up and connected. I put in the HE's next to last and then the exhaust last.

yep, you almost HAVE to wait until last, otherwise you have to do it twice to get everything lined up... just don't tighten the H/Es down tight until you are sure everything is lined up properly with the muffler and hanger...
