I would be concerned with it eventally sepperating from different expansion characteristics and being sucked into the backside of the valve or even into the cylendar.

If anything the epoxy will probably work better on the plastic because it doesnt hold heat like the aluiminum does. Just a little speed tip for you guys: The Fast two piece manifold is prone to internal leaks, which, costs some power. I recommend sealing the seams with RTV silicone. I have seen over 15 horse gains.
