Right distributor fires 1-4-6-7, left distributor fires 5-8-3-2. These numbers should be emobssed in the distributor caps. I don't remember which bank is 1-2-3-4 and which bank is 5-6-7-8 but the bank that's slightly forward of the other bank is the 1-2-3-4 bank. I think the right bank is slightly forward of the left bank but double check.
