My local machine shop ordered them from pro max, they are supposed to be going on a 360 with a 4 inch crank.
The engine is getting built by a good friend of mine, next time I stop in I will see if they can flow them.
If you were closer I would flow and speed check them for free. I liked what a saw from the non cnc'd ones. They made Edelbrock heads look like imported JUNK.
