I would like you to consider adjustable roller rockers over fixed, not much more money and to me it just makes sense to upgrade to adjustable rockers. I set mine(rockers) spring and fall and when I do adjust them they are never off. There are a few kits out there but I went with Mopar, super nice peices.
