Complete Motor with headers.

I can't see installing the engine with headers installed... I HIGHLY doubt that is possible.

If you want to eliminate as much trouble installing the headers as possible, then get TTI headers. I actually replaced my side exhaust headmen header system with TTI and am very happy with my decision. All you need are the headers, I opted for the whole system. Also, get the ceramic coating in and our to decrease under hood temps considerably.

My only complaint is that they recommend you use other headers to break in the engine to avoid damage to the ceramic coating. That's just silly, they should be designed for engine break in... since I did use them to break in the engine (two engines) they are dull. And I paid extra for the polished ones...

Also, yes you can install the engine with the bellhousing but you will likely scratch the fire wall paint. ( but worth the scratches!)
