I'm still not near the place I have to decide.

Yes, I did! These pipes are huge.Did you get the torque inserts for the head? .....
They're supposed to help get back some of the low and midrange power a large headpipe like this loses.
If I was mounting these, I think I would change the order of things like I did with my "homemade" inserts on my '78. I stuck the insert into the head 1st with some Yamabond then placed the gasket and pipe on top of it .....
This will fill in more of that step machined into the port for the stepped end of the stock headpipe to fit into. But as you can see in the insert pic in the previous post, it doesn't fill the step completely, and that left over groove is said to be detrimental to flow. My homemade insert didn't fill the step completely but I was able to add a pipe ring to finish the job .....
You can't do this with the gasket installed first because there's no way to know how much it will compress when tightened down, so you can't determine the thickness of the filler ring needed.
How does it fit if you put it in 1st, then the gasket on top of it? The object here is to try and fill in that step machined into the head. Putting the TPO in 1st will fill more of it, maybe all of it.
Thanks. That’s exactly what I wanted to know.but they do indicate OEM parts.
