After pulling the head on my M104 engine, and during the "first blush" inspection, it seems there's either a crack or a steam trace on cylinder #6 shown here.

Does anyone know about Bill's Cylinder Head Service in Phoenix? It doesn't look like he has any web negatives that I can find. Though I can send the head to Metric Motors in L.A.(suggested by 73Elsinore), I would prefer to drive it to a local machine shop in Phoenix, that is if I can feel confident about it.

Thanks!

Michael B.
