Awesome. I cant believe I got an answer that fast. Thanks guys. Now I just have to get the broken bolt out of one of them.... Actually I have a question about the guide plates on them. Are they factory that way? Can I remove the guide plates (are they screwed or pressed in). And Should i use guide plates or self aligning rockers?

I would use guide plates. The rocker studs screw in, so you just have to unscrew them to get the guide plates off. From what I hear, some of them came with guide plates, and some didnt. Mine had them. Good heads though, respond really well to porting.
