I have a stock LS motor with 130k on it. I plan on building the internals of the bottom end for turbo. My goal is for no more than 400 hp. Probably between 350-400hp. Will the stock head be able to handle that much power and boost from a decently sized turbo? Will I have to upgrade the head to achieve that amount of power? Just trying to get an idea of what I am getting myself into before go through with the build. Thanks

 

i believe that a good dyno tune would be worth the money instead of putting it into a head, less bling bling but more reliable and powerful. however if money is not an option a reliable vtec head would flow better than a ls head.
