Planning first engine build, need help

You're gonna end of with 800-1500 in machine work alone for a fresh rebuild. You're livin in a fantasy world thinkin you can do the whole thing for that.

What I would do is tune what you have first. You might save a lot of money. I would adjust the valves to .010 intake and .018 exhaust. It will run well there. Bump the initial timing to about 15* idling hot. Get a vacuum gauge on a manifold vacuum port.....there are two on the passenger's side front of the carburetor stickin out of the base plate...and see what the vacuum reading is. I bet you don't have enough initial timing. Classic mistake. You can learn a LOT by learning hot to tune one.
