302 casting potential?

I typically use 1.88/1.60s in 302s if I need to use them. Because I can move the seat out which is better for power and makes the chamber a little smaller. I do a little blending and gasket match the intake, and that's it. IMO, if you are then going with larger intakes, using more port, requiring more work and cash... You should just start with a better head. Even a factory magnum or even the EQ Magnums would be a better choice for a low budget 318.
