This is for my son's c30 dually. He is 17 years old so I really do not not want his truck to have a lot of HP. I would think 200-250 might be enough for him to drive on the street. Also, I think the current head on this truck has a valve problem. I am going to install this one and maybe redo the other one at some point. Right now, he is only into it for 200.00 so I guess that's not too bad (got it checked out at a machine shop). This is not his daily driver.

So it is 194 head??? I was not sure. It does have 1.94 valves in it.
