Ok that sounds good that means in probably going to have to stud the head or something cause when I get this pump on I will probably sneaking up close to 40 pounds of boost and I kinda planned on timing it to bout 16* and I am going with the 4k springs and also getting 60# valve springs to keep from floating any valves.
