Cheap Magnum Heads and some porting
Well this is what I have doe so far. I'm hesitant to take out to much metal. This is my first porting attempt and I'm not sure how much metal to remove.
This is what I started with:
I started with blending the valve throat into the as cast intake port. I know I don't want to open the valve throat itself. I'm using a dremel tool and a tapered grinding stone. I think I can go a little farther than what I did in these pictures. I know I want to leave the intake port surface rough though this helps keep fuel in suspension.
Then I moved into the combustion chamber. I radiused all of the sharp edges, to reduce the chance of any hot spots. I figured I will polish the combustion chamber to help reduce carbon build up.
