By studs do you mean the bolts that hold them on? I just used WD40 and a 3/8 drive (can use a 1/2 drive) with an extension and/or more added on to get the bolts off the intake&exhaust manifolds.
Every Slant Six ever built used studs to affix the manifolds to the head. Over the years some people switched them over to bolts for some reason.
I have the nuts off, the manifolds off, now I'm trying to get the studs out of the head. I'm going to barrow a torch from a friend so maybe I'll have them out by tomorrow.
