Is Moroso A-B epoxy good stuff? Anything better?

Run and brass sleeve in there. The sleeve will be supported around the pushrod hole. It's all too thin right now.

Then just smooth/fine sandroll until you see the sleeve poking through.

I think I will do that, the runner that has the 2 big holes has to be thin, I poked those with a thin pick. Thanks for the suggestion! What would happen if you were to put the epoxy in the runner, and on the outside of the runner where the pushrod is? With no brass sleeve?

Mettildart,can give you pictures,of stock Magnum ports. WHY?

Cool! I also have a set of cracked ones in the basement I forgot about, I could get a pic of those too. I was saying I wish I had a pic of stock intake runners to show Artie how big the pinch was on magnum heads, to show why I was opening them up so much.
