Who has experience with this head is it worth it. its not super expensive like others heads Out there so I am attracted to it for the price. I’m running a Borg Warner big turbo kit on my car but I want more power lol. I want as much power as I can get I’m probly going to upgrade my turbo out to a S257 fmw Here in the future. how much power can I expect out of a head, what about others heads.
