Has anyone out there installed or seen one installed? Unfortunately I do not have a link to a photo. But it is not a conventional plenum. It is two pieces that , apparently, fit over each bank of cylinders. It may be the bees knees , or it may be junk .

Thanks ,
Tom
 
Could this be the photo?

I'd be interested to see how they achieve a leak free seal around the pushrod tubes and cylinder bases. It "looks" like there is no positive seal there. If there IS contact with the pushrod tubes, how do they ensure the tube itself is not preloaded with various levels of presurization? Pushrod tube seals dont like radial preload, in my experience.
 
Thanks for the photo. Yes , that is it . It uses silicon baffle material to seal around the pushrod tubes. But it appears that the primary support for the piece is the area anchored to the cylinder head. The pressurized air in the baffle will be trying to rip it off. The seals will provide some resistance but I have to wonder it it end up riding in the inside of the cowl.
