I have head studs and you don't have to remove MC. Just unscrew the top 5 studs, ARP studs allow you to remove them with an allen wrench, and pull off. I install the lower 5 studs and use them to align and set the head down. But the top studs will be a little tighter than hand tight because they will have either thread sealant or silicone on them because they enter the water jacket. Just get some ARP studs that allows you to remove them with an allen wrench.
