I thought I'd share some pics of my gutted and modified LIM that I put some of my own twists on for my tumble port heads.
Here is a pic of the bottom side of the LIM. I reshaped the port heavily as you can see.

The top side is still split port, but it was also ported.

The LIM was gutted and the secondary butterfly shaft holes were filled with Kop Coat. I reworked this LIM to work better with my 3L aluminum UIM and the tumble port 3L heads.
Thoughts?
