Spend the money and get ARP head studs, there are many reasons. best of all you can re-use them if you have to change head gaskets.....

HEAD STUDS vs. BOLTS...
A TECHNICAL DISCUSSION from ARP

ARP’s factory Tech Representatives are often asked which
is better, cylinder head studs or bolts. The answer, invariably,
depends on the installation. On many street-driven vehicles,
where master cylinders and other items protrude into the engine
compartment, it’s probably necessary to use head bolts so that
the cylinder heads can be removed with the engine in the car.
For most applications, however, studs are recommended.
And for good reason. Using studs will make it much easier to
assemble an engine (especially a racing powerplant which must
be serviced frequently and quickly!) with the cylinder head and
gasket assured of proper alignment.
Studs also provide more accurate and consistent torque
loading. Here’s why. When you use bolts to secure the head,
the fastener is actually being “twisted” while it’s being torqued
to the proper reading. Accordingly, the bolt is reacting to two
different forces simultaneously. A stud should be installed in
a “relaxed” mode – never crank it in tightly using a jammed
nut.
If everything is right, the stud should be installed finger
tight. Then, when applying torque to the nut, the stud will
stretch only on the vertical axis. Remember, an undercut
shorter stud will have a rate similar to a longer, standard shank
stud. This provides a more even clamping force on the head.
Because the head gasket will compress upon initial torquing,
make sure studs and bolts are re-torqued after the engine has
been run.
