"everything is in very good condition. the only think
thats tricky is the head studs. They had to be
grinded down so the alan key on the top of the studs
is gond for some of them. they had to be done this
way because of the roller rocker clearance. you are
gonna have to use vice grips to torque down half of
the studs. I am talking about the internal ones.
external is all good. Ask people on thirdgen about
the twisted wedge g2 heads. thy make power but are
tricky to put on. I left in the spark plugs also,
they are a bit fouled, but at least you know whick
ones to get. "

this is what i got for an answer, am i gonna have to replace anything, or is this ok?

 

not sure about heads, there are internal and external studs

and am i gonna have to replace the studs? and what does he mean allen key?? i thought allen key was just on top of the roller rocker.
