Why do I never hear of people doing this to diesel?
I don't know anyone that sells p&p'd heads other than Elite, and if you need new heads the difference is insignifigant. I had mine done by a friend, but off the street average Joe would pay around $300 for the p&p(mild), from any reputable machine shop. What do you get? I got 10-15hp and a wee bit off my 1/4 mile times. Airflow is the weak point on the 6.0, so if you have the coin it might be worth it due to reducing backpressure. My truck dynoed all over the place 500-560, and consistently clicked off 13.0 on 35's with 3.73's, which equals around 537hp. Here is a graph pre modded heads with a leaking boot for your reference. I know that Rescue claims 550+, but does not post up his dyno graphs, so take his "advice" lightly. The 6.0 is a tough motor to mod and expect reliability, and I had three of them and tried, but switched to a 6.4 and could not be happier, 600 reliable hp with bolt on's sure beats fixing a tempermental 540hp 6.0 once a year.Ok thanks guys so not even worth the hours of labor to do then?
205's with proper air and supporting mods should push around 600 on fuel. Depends on having the rest of the setup dialed in too.alrighty guys thanks for all the info. On elites site is says that 205cc injectors are the highest you would want to go on a factory hpop is this the case? What kinda power you guys laying down with 205s?
