Hello everyone I ordered most everything for my last engine through Jon. I used P51 heads and at 547 cubes it made 940 hp. It also got sprayed with a twin fogger 700 hp worth. As with most things 4.80s just don't seem fast enough anymore. I got a C&C 5 inch borespace block and my plan was to use C 441 heads on it. I have been getting opinions that the C 441 doesn't like nitrous in large quantities and I should use a wedge head for my nitrous. So I thought I would ask the guys that for sure know. I am very at ease reading plugs and tuning big hits of nitrous. But if the heads don't like it I will go a different way. Any info would be great thanks for reading.
