Wtf - roller rocker

First things first.

You need to contact Mike at B3 racing engines. You need to correct the geometry. There is no way those rockers just bolt on. No rocker with a roller tip will just bolt on. Well...they will bolt on but they won't be correct.

There are many threads in the small block forum covering this.

After you correct the geometry, then we can discuss other issues you may have. Start with geometry first.
