While I was able to engineer in the correct angles for the intake manifold to mate to the block and heads when I designed it; the printer left too much slag on the bottom surfaces and I had to fixture it up in my mill to cut those angles for a proper fit. This material is very brittle and I was relieved that it took the vise and milling as well as it did.
I also added a couple more magnets to it.
The block received two more magnets too. As well as brass tubing under the thermostat housing and the distributor to positively locate and align the manifold.
