So, what do you think so far? Gots to be the hardest way to make an intake manifold, right?
The next step is to machine some oring grooves on both sides of the runner legs. I was using Motoseal at those mating surfaces and only 2 bolts to hold it all together. As you can see in the last pictures, each runner leg now has 4 bolts and will use viton material rubber orings for a better fail safe seal.
Orings are also used to seal the throttle body, the poppet valve and the plenum cover to the plenum. You can see the oring groove for the plenum cover in post number 18.
