well, here's my first angle mock-up. rough, but I think I can make it come together. starting with a small bit and working up should help eliminate any 'accidents' due to a hung-up drill bit.
I've done some mock-ups with the gasket and mfi manifold, and I don't think I need to fill the cis cutout. also, I intend to use the plastic spacers under the manifold which seems to eliminate the problem. I'll post a pic.
