first time rebuilder?
 

OK here goes Im rebiulding and 87 t2 motor for my 84 se. Im going to be porting it using a RB template. I was looking at the plates as I was getting ready to start I realized that the ports in the center plate are way smaller that those in the two end plates. My question stupid as it may be is, do you port all 4 faces of the plates to the same template or are the ports in the center plate left alone or ported to a different size?

I lined the template up on both the side and center plate and it just seemed like a lot of metal to be removed.
