I have a stock '89 318 LA style and I want to put headers and have my dual exhaust redone. I plan on dropping a 360 Magnum in the next year or so. I am wondering if the LA headers will still work when I do the swap? I do know that I will have to plug the AIR injection ports on the heads. I just don't know what size they are. Any help would be greatly appreciated. Thanks.
