I am assuming you mean a lump head as I was just reading about. I am looking for about 250-300 horses if that can be done and run pump gas. I also like the look of the multi carb and since it will probably be going in a roadster, I do want the look. Can my local shop do this to the head or do I need to ship it out? Also, I don't plan on doing much until summer at the earliest anyway.
