     So I was rebuilding a Standard Vanguard engine for an early Morgan =
+4. It uses all TR3 internals, but has a different head and manifolds. =
The head studs are 7/16ths diameter instead of the TR3=E2=80=99s =
=C2=BD=E2=80=9D studs. A SV head torques on to 55 Ft/pounds instead of =
the TR3=E2=80=99s 105 ft/pds. If you torque a TR3 head on to a Standard =
Vanguard block and torque it to 105 ft/pds then the block will crack =
above the drain spigot. I have two cracked Standard Vanguard blocks that =
came with my cars. One I had stitched together and am running it in a =
car now.

     So I called ARP and told them I needed head studs for a rare car. =
The guy on the phone said =E2=80=9CGo ahead and hit me, I=E2=80=99ve =
heard of just about any car=E2=80=9D. I told him a needed head studs for =
a Standard Vanguard engine for a 1953 Morgan +4. I could hear crickets =
on the other end of the phone. The guy told me that he had never heard =
of any of those words and wanted to patch me through to custom =
fabrication (and greater expense). I told him =E2=80=9CHold on, I need a =
7/16th stud 10 and a half inches long, coarse on one end and fine on the =
other=E2=80=9D. He said that that was a head stud for a 302 Ford. It =
cost me $76 including shipping. They worked great in my car.

I used ARP head bolts on my last Stag. I torqued down the head, but =
never in the last 5 or so years did I re-torque the heads. I recall =
speaking to a technician over at APR and he said no need to re-torque  I =
have not run into an issue. But am wondering what other's have to say.
