    I'll try to answer my own question and those of you with judging experience please help me through this if my math is incorrect...
    .
    There are 25 originality points assigned to the 3 items on this line: intake manifold (1), bolts (2), gaskets and seals(3). 25 originality points divided by 3 separate items is 8.333 points for the intake manifold, 8.333 points for the bolts, and 8.333 points for the gaskets and seals. So now we're down to 8.333 points since we are only talking about the seals and gaskets. For my intake manifold there are a total of 4 gaskets/seals - left and right side wall gaskets as well as the front and rear rubber end seals. 8.333 points divided by 4 total gaskets/seals is 2 points per gasket/seal. And since we're only talking about the front and rear rubber end seals we're only dealing with a total of 4 originality points for BOTH the 2 rubber end seals.
    .
    Since the 2 end seals are made from rubber orange paint may or may not adhere to the end seals. But let's just say (for the purposes of this conversation) that orange paint will NOT adhere to the silicone and will be more easily seen as non-typical.
    .
    Here's where I don't know (because I don't know how to assign point deductions) if there is a standard deduction or if we use the CDCIF matrix (Configuration, Date, Completeness, Installation, Finish) where each non-typical item is judged is 20% of total originality points.
    .
    If we're using CDCIF, then which of the 5 applies to the non-typical gasket/seal? Configuration deduct (because the rounded GM tab is not visible)? Installation deduct (because the rounded GM tab is not visible)? There's no applicable date, and I'm presuming the non-typical gasket/seal would be complete. That leaves Finish, and if the silicone rejects orange paint then I could see how the car would receive a deduct for the Finish part of the CDCIF. So, now let's add up all the CDCIF point deducts... 60% CDCIF deduct for configuration + installation + finish. 60% of 4 originality points for BOTH the 2 rubber end seals is 2.4 points.
    .
    Did I do the math correctly to come up with approximately 2.4 points lost due to using Permatex Ultra Black silicone gasket instead of rubber end seals?

      Brian, Put the intake gaskets on DRY. Then fit the intake and snug it up without any torque applied. You will get your answer easily. Then when you take the intake back off, take a photo so everyone can see the orientation of your nice GM tabbed gaskets.

        Brian, Great math, however, the judges wouldn't evenly apply the 25 points. You might see 20 for the intake and the rest divided up. You might see 15 for the intake and the rest divided up. Anyway you slice it, there is not enough weight given to the end seals for a 1 point deduction. That is why I said,...."Shame on those judges for taking a point"! Just a note to you is the proper score. No points deducted.

        I guess we all need to pay more attention at the CDCIF school.

        Enjoy the weekend! Joe
