This truck is just going to be a daily driver, so don't want to get involved in the hassles of changing this and that to get a little extra juice. Trying to keep it simple...

Hehe well now we know it is both the 4.8is and 4.4 that have the different manifolds on an e53 compared to the cars. -Rich |

So, after thinking about this, I am going to make a jig to place on the existing studs of the head and use the old X5 exhaust manifold as a template. Than use the jig to drill through. But, need to figure out how to exactly match the x5 manifold to the cylinder head so it is located perfectly and that I don't get any leaks once I connect to the exhaust system. Thoughts anyone?

swapping N62 motors
I would just bolt the manifold to the head apply a liberal amount of lubrication and use the manifold as the jig. Aluminum of the block will drill much easier than the manifold, if it lines up well and centered shouldn’t damage the manifold at all. - Be sure to center punch the head so your bit doesn’t wonder

I agree, the manifold will work fine as a jig. Bits tend to drill pretty perpendicular. Getting the threads square with a tap is harder than the drilling. You might want to get a special tap that can thread the hole all the way to the end as opposed to a regular tap that is really made for putting holes through flat plates where the hole is drilled all the way through the material: Something like a: Thread Forming Tap (Tru-Flo™) is likely better for this job. https://www.natool.com/engineering-data/tap-style-guide I would also add a drill stop to your bit so that you don't drill deeper than stock. If you were to drill too deep. I don't know what you would hit if you drilled too deep but it is better to not have to figure it out. Something simple like these from amazon will work fine: https://www.amazon.com/Piece-Adjusta...15682791&psc=1 -Rich |

Thank you Rich. Good advice. I am just trying to make sure that the manifold is exactly where it needs to be on the head. Need to pull the existing studs. Than, take a straight edge, using the old stud holes as alignment, to mark the new drill holes. Going to just take my time and measure 100 times before drilling. Will take pics and post them up for others down the road.
