BES does not build winning combinations based on flow numbers, but, everyone asks for them as a baseline, and that is why we are posting them. Flow numbers will vary from bench to bench.

We have many programs for a huge selection of domestic cylinder heads. If you don't see what you are looking for on the website, give us a call at (812)-576-2371.
