So I have these nicely chromed headers and I need to know if there is any other modifications I need to make to install them. Either to the headers or to the engine.

1990 460 in a F250.

It seems some threads say weld on bungs for sensors are needed and others say egr removal but retain the valve. Or remove it alltogether and block it off.

Im confused and would like the definitive answer from someone that knows for sure.

 

Make sure you either remove or at least replace the cat with a high flow unit or a significant portion of gains the headers should add will be negated.

 

Well since they are LTs you are going to need custom exhaust from the headers back.(you most likely knew that)

O2 will need to be redone. Not sure if those headers have the bungs already in them.

Truck 4x4?

P# for headers?

 

The part number is 89460. I really hope I dont have to ad o2 sensor to the headers. There must be another way. There will be no cat and duals.

 

Yes they dont have bungs in them already. Its really not hard. Just weld a bung into the exhaust pipe right after the headers.

 

Ok, so I need the sensor. check.

Now what about the EGR junk. Keep the valve and block the tube? Remove everything and block ????????????? Is there a kit?
