hello all, i'm installing the rocker arms on a 99 CRV B20Z2 engine and got the rocker arms out of sequence. They all look alike, but each has a number from 1-8 stamped on the side. How does the sequence work? Or can they be placed wherever in any order? These are the "loose" rockers that sit there individually under the cams. not the rocker type that has a shaft running through them. Thanks.
