There is a 'Yes, but' here.  For one thing, some of the Stude bolts,
such as the water pump and water manifold bolts are odd lengths.  Some
of the water manifold bolts have a long hex with a stud for mounting
accessories.  Are these included?  Are the appropriate lock washers
(either split or  external toothed, depending) included?  

Also be aware that virtually all the original bolts were Grade 5 bolts
(3 slashes).  Virtually all easily available stainless bolts are Grade 4
(2 slashes) and thus require less torque.  Torqueing a Grade 4 stainless
to Grade 5 specs will either twist the bolt or cause it to gall.
Hi-strength stainless bolts are available, but neither cheap nor easy to
find in the size you need at the moment.  Type 304 is the standard
alloy, A286 is the most common high strength alloy. I understand Boeing
Surplus is a good source if you live near there.

Another thought - if using stainless bolts with the battery cables, be
sure and use Type 316 stainless bolts (available from marine hardware
dealers), as Type 304 does suffer corrosion from sulfuric acid.
