i am replacing my callaway parts with steedspeed and pope. does anybody know what size studs i need to use for manifold to the head and manifold to turbo? i know i don't need to replace the bolts to the head but would prefer to have studs instead of bolts.

length, thickness, thread pitch, etc. thanks in advance
 
all 3 flanges will work with the exact same size stud? reason I ask is because I thought the manifold to head studs were thicker.
 
They will work with the head to manifold. Manifold to turbo. They are the right size to work turbo to down pipe with the stock or ghl down pipe. I don't think they will work with the pope down pipe. i think that needs special hardware
 
ya I just purchased a pope and I knew he supplies the allen head bolts for the turbo discharge except for 1 that has to be a stud. thanks for your help. may have more questions as they come up.
