Not to hijack this thread, but...you guys like RAMM, yellow rose, gregconn and others...where and how did you learn the art and nuances of porting and head flow? I would never feel comfortable grinding and experimenting on a set of decent LA heads, especially not having a flow bench. It's pretty obvious that even what looks like an obvious improvement can actually slow down and stall air flow, create swirl and back flow where it may not be wanted, and other issues. Just curious? I can start another thread for this if anyone cares to elaborate. Again, not meaning to hijack here, just curious.
