A friend of mine built a 420 using those heads. It made about 740 hp with a t-ram and 2 alcohol carbs. Not a real impressive number by any means. His car weighs close to 3000lbs and has run 9.20's at 143-144 after just a few runs. His best previous numbers were in the 9.50's at about140 using AFR 23 degree heads. The 18x's were not a huge improvement over the 23 degree stuff he had before when you take into consideration the added engine size. There are some very good 23 degree heads out there and probably run as well or better.......
