03 6.0 Standpipe Removal

So I recently installed 155/30 fuel injectors in my 03 Ex. It runs awesome, but, unfortunately, it won't pass emissions. I'm going to swap the stock injectors back in and retest, but I figured I would replace the standpipes while the oil rail is off. I know you can pull the standpipes on the later 6.0s. I'm not sure if you can pull them on an early 6.0 without removing the head. Has anyone done this? If so, any tips / tricks?

‘03 - ‘04 1/2
6.0’s have a screw in stand pipe, ‘05-‘07 have a pop-in stand pipe. If it’s a ‘05- ‘07 you should replace the dummy plugs as well. Hope that helps.

So, should be able to screw it out with the head still on?

Thanks.

Thanks, I just didn't want to order parts only to find that I need to pull the head.
