Okay I know this is a off the wall question, but I am some custom parts for my 340 and the front of the heads measurement is very important and am not ready to purchase the edelbrock 60779 RPM heads I will be eventually using. But I need to know how much further the heads (especially Drivers side) overhang the block, it looks to be between 1/2" to 3/4" but any more accurate help would be greatly appreciated. See photos for exactly where I'm talking about.
