Is it possible to install the header without removing the head? I'm guess it can't fit through the top so is it possible to thread it through the bottom?

 

from what was said from jbp youd have to remove intermediate shaft from bottom or valve cover from top but that prob wont even work

 

oh yes you can do it without head removal, from the bottom, but i had to lower the cradle, because thats what the guy helping me wanted to do and i didnt feel like arguing, but if i was alone i would take out the axle because i think its easier. if you do that then buy some transmission fluid for what comes out. deffinatly get the ball end allan keys.
