header bolt
One of my header bolts fell off . As I was trying to put it back on it didn't fit as the header was bothering it . I really don't feel like taking half the header out . So can I cut it the bolt so it can fit?

Your header shifted a little, its not a big deal. Does it leak without the bolt? If its leaking you most likely going to need to replace the gasket.
If it is not leaking there is a couple of things you can try. Install the bolt when the engine is hot,,, some times the header will expand more then the cast iron head Or you can loosen all the bolts on the side and use a pry bar a just shift the header a little.
The hole should only be off a little, worse case you could use a dremel like tool to open the hole just a little but you need to be sure not to damage the threads.

You really should get this fixed. Leaking exhaust out is not a big deal but it will also draw fresh air in. That woull throw off your O2 sensor and can hurt your valve. If you have the money or your doing the job yourself you should think about doing the head gaskets with the CAM. They can be a weak point on the motor if they have not been replaced yet. New Cam can equal more power, more power equals higher pressures in the cylinders. That can be bad on a 13 year old head gasket.
I have seen car that have bottomed out and bent the exhause, this can put a lot of stress on the header. Some times all the needs done is to losen the exhaust clamps and that will let the header come back.

The rebuild is a huge step labor wise. The cam and head gaskets can be done with the motor in the car. Step one to a rebuild is remove engine. Pulling the motor is not a major deal but I would guess it takes me about 3X the labor to pull the 4th gen engine then it would take to do a 3rd gen. But I have pull 100s of 3rd gens and only 2 of the 4th gens.
How many miles are on the motor? As a general rule it is not worth rebuilding a high miles motor. The machine shop work alone can cost over a $1000. The biggest issue is the cylinders and cranks journals are not round anymore. If you just install new rings and bearings in an engine with high miles it can run worse and smoke more than before the rebuild.
Decent rebuild will cost you $2500-$3200 on an average high miles motor. What most guys do is buy a low miles 3800. I have seen 2008, 3800 series III motors sell for $800 with 20,000 miles on them.
