Sisell has a nice product, Aussie Speed seems to be the go to for blown motors. I worked with a lump port from Mr6HotRod, my first port conversion. It wasn't that bad , just took my time opening up the ports being careful not to remove too much material. I CC'd each port trying to keep the size equal. Here as some pics of the lump port.
