It's all maths RE fuel, looks like 12mm and 2.8mm is best option but I've not found one yet. The pin on a Cummins is bigger so needs tweaking to make it fit (like 0.5mm). I ran a large 3 to 4mm camplate with a 10mm and had a run away event so just went with the 12mm I had available.
Rotation doesn't matter for an idi camplate as it's a symmetrical curve. Di camplates can have an actual profile on them the leading edge.
10mm head, 2mm cam, 15.7mm3
12mm head, 2mm cam, 22.6mm3
12mm head, 2.8mmcam, 31.6mm3
10mm head, 4mm cam, 31.4mm3
12mm head ,4mm cam, 45.2mm3
