To me this thread is not specific enough. Are we street driven only or
Race only.
10 degree,super 7 or 8 degree locks.
Generally a single lock 10 degree that do not butt together is an all out race setup. 8 degree that butt together can fail and drop a valve at high spring load/high rpm.
Stock LA small block heads was what I generally had in mind, but I think the discussion is worth all that you brought to the table. I just added this to the original post, thanks
