Usually, depending on the headers you have to lift the engine a little bit. It is much easier to have the semi-mounted up when you drop the engine in. I didn't have to jack up the engine to get my flowtechs in but it was a royal pain in the rear. I would kinda lay them in place as you were carefully lowering the engine.

fordman and fordfan. Wow, thats kinda hard to distinguish. On low performance engines the high temp paint seems to hold. THe paint on my headers vaporized soon after startup and they are starting to rust. Not all the way through or anything. Just on the surface. Hedman has a pretty good reputation but a cheap header is a cheap header.

I put Headmans on mine, but I resprayed them before I put them on. The sticker tells you the "paint" if for rust prevention for shipping ONLY. Wonderful. I put some hi heat black on them. They smoke like a coal furnace for about an hour til it all burned off and now they are just kinda charcoal black. It's been a few months and NO signs of rust yet.

i think it all depends on what you use your truck for too. for example i use mine every weekend mudding and of course all of the water and mud splashing on them has had a huge impact on how fast they are rusting out. (which is pretty fast) but i have on my tar baby the same hedman headers and they have lasted 4 years and no signs yet, so i think that what you do with your truck is a huge factor.

Wrapping headers is a bad idea-they retain moisture and speed up the rusting and aging of standard headers. Good cerma coat headers are of course the, more expensive, answer. But they will be last time you buy headers.
