i can't draw a diagram, or take a picture, but i can walk you through it. did you look at the pipes going to the back of the heads??? If not, look now. I think it is really only one pipe that goes back there, but it splits into 2 (to go to each head). At the end, where they bolt to the head, they have a little flange which is a thick piece of metal (you have to look at it to understand this). Well, what you do is cut the pipes off of the flanges right up against the flange itself. Unbolt the flanges from the heads, and totally flip them around so the opposite side of them are against the head now, which is totally flat, so it will block over the hole in the heads. And as I mentioned above, i also put some permatex around the hole to make an air tight seal. I hope this helped, I sort of rushed through this the first time...sorry about that. Basically, you really have to go look at what you've got to fully understand. You can unbolt them from the heads without taking the heads off. Removing the upper intake would give a lot more room, but that's about it. Feel back there for them, take them off and check it out.
