Darts has a new upgraded Pro 1 head called the Platinum. Chevy HP mag just had an article about it. Anyone tried it yet?

Higher plug, more unshrouded intake valve, 5 angle valves, new valveguide area for better flow. Yields 40lbs and 20hp over the iron eagles and 10lbs and 23hp over the regular pro 1s on a 383ci/460hp small block.

Contact HVH Cylinder Heads out of Knoxville, TN. They did quite a bit of R&D for that program.
