I can't tell you much for intial timing yet, but I would think 12-14 would do much better. How do you have your curve set on the distributor? Using vacuum advance or mechanical?
There, answer these any we may have a little better picture of what you have.

And not really sure how to adjust the rockers. I never had rollers before. Thanks for the help. It is in a 57 Willys Wagon with 456 gears and an automatic. Pertronics distributor vacuum advance
