Slot the holes in the gaskets? No. I guess I may have explained things in a confusing manner. Rereading my post yeah it is. There’s no cutting or moving the gasket obviously. Properly stated, the actual intakes bolt holes are elongated to be able to move it, in my case forward so it lines up with the gasket which lines up with the head ports. I’ve had a few intakes (gasket/port matched) on my TF heads and haven’t had any mismatch: roof, floor or sides. This is the only intake that needed the holes elongated in order to match up. I had a new Victor 340 I bought and ported late 2021 and it was fine, other than dinky ports. This newest casting is something entirely different.
