It uses all TR3 internals, but has a different head and manifolds. The head studs are 7/16ths diameter instead of the TR3’s ½” studs. A SV head torques on to 55 Ft/pounds instead of the TR3’s 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.<o:p></o:p></span></font></p><p class=MsoNormal><font size=3 color="#1f497d" face=Calibri><span style='font-size:12.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> So I called ARP and told them I needed head studs for a rare car. The guy on the phone said “Go ahead and hit me, I’ve heard of just about any car”. 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 “Hold on, I need a 7/16<sup>th</sup> stud 10 and a half inches long, coarse on one end and fine on the other”. He said that that was a head stud for a 302 Ford. It cost me $76 including shipping. They worked great in my car.<o:p></o:p></span></font></p><p class=MsoNormal><font size=3 color="#1f497d" face=Calibri><span style='font-size:12.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></font></p><p class=MsoNormal><font size=3 color="#1f497d" face=Calibri><span style='font-size:12.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> -Bill Brewer <o:p></o:p></span></font></p><p class=MsoNormal><font size=3 color="#1f497d" face=Calibri><span style='font-size:12.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> Tehachapi, CA<o:p></o:p></span></font></p><p class=MsoNormal><font size=3 color="#1f497d" face=Calibri><span style='font-size:12.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></font></p><p class=MsoNormal><b><font size=2 face=Tahoma><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";font-weight:bold'>From:</span></font></b><font size=2 face=Tahoma><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Sujit Roy [mailto:triumphstag@gmail.com] <br><b><span style='font-weight:bold'>Sent:</span></b> Thursday, September 5, 2019 3:10 PM<br><b><span style='font-weight:bold'>To:</span></b> Triumphs<br><b><span style='font-weight:bold'>Subject:</span></b> [TR] anyone have experience using APR head bolts<o:p></o:p></span></font></p><p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:12.0pt'><o:p> </o:p></span></font></p><div><p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>I used ARP head bolts on my last Stag.
