I'm curious about the ported m1, I noticed the other day the ports are pretty bad from one side of the intake to the other. I compared it to some edlebrocks and as much as people complain about them the eddys were much better.
I'm bummed out, when I received my tf heads I opened one box looked at it and put them on the shelf. Since my rods were backordered I couldn't do much. The other day I opened both to check gaskets on the intake ports and comparee to some intakes. One of my heads was damaged before packing. The boxes are perfect. I have to call and see what can be done.
