I am putting my 1JZ back together, well the front end, after putting in new cam seals, water pump, etc and before I put my tensioner and belt on I want to make sure of something. I know I have the exhaust gear on the exhaust cam and the intake gear on the intake cam but I want to make sure I have them on correctly. Are they are 0 offset, meaning the mounting surface is directly in the middle of the gear or is there a side that is supposed to be facing out and a side that's supposed to be facing in?
