I saw that article recently and the pics of clamping force between the three. Looked like cometic had the least clamping force on the clamp ring around the cylinder. I thought I read that cosworth was just coated cometics or is that wrong? I have used cosworth in the past with no issue at high boost. Guess ill be giving them a call.

Let's talk studds. Is there a better option than the standard ARP? One that doesn't need to be tq higher than 90 ft/lbs as that is what I had the tq plates at when it was honed.
