Modified the intake on Saturday to accept a 4500.
4500 gasket on the 4150 flange.
Sharpie'd an outline around the gasket.
Drilled holes along the lines I wanted to cut and took a ball peen and tapped the big chunks out. The casting is really thin where the clovers are because this intake is available in both flanges. If I were doing it again, I'd drill smaller holes along the perimeter so I would have less material to remove with the carbide.
I countersunk the alumimum screws, then drilled and tapped the new stud holes. The new holes actually go through the heads of the filler screws.
Finished. I also drilled and tapped a vacuum port in the back because this manifold did not have a vacuum port.
Intake gaskets will be here today and I maybe I can find some time soon to button it all back up.
