DOES PIERS OFER A REGROUND MARINE CAM AND WHAT IS DIFFERENT ABOUT THE HEAD STUD KIT FROM PIERS AND THE STOCK HEAD STUDS

 

Yep, he has a marine regrind I heard <br><br>The head studs are just that, studs instead of the factory bolts.<br><br>Don~

 

1STGEN:<br><br>I have the &quot;ARP&quot; Hardened Head Studs in my 96' Dodge<br>CTD. I had them installed my Scheid Diesel when I blew<br>my head gasket last January. <br><br>As &quot;Don M&quot; already said, the head studs are hardened<br>&quot;studs&quot; NOT bolts which Cummins uses in the engines.<br>The advantge of the studs over the &quot;stock&quot; bolts is <br>they don't &quot;stretch&quot; when they are tightened. After<br>my head came off, Scheid Diesel checked the length of<br>my &quot;stock&quot; bolts and found that all (28) of them were<br>&quot;out of spec&quot; with regards to length! They had &quot;stretched&quot;<br>that much!! Another advantage I could see was that the<br>ARP Studs were &quot;torqued&quot; to 120ft. lbs. versus 90 ft.lbs.<br>(plus a quarter turn) on the stock Cummins head bolts.<br>You could &quot;feel&quot; the difference in the way the studs <br>tightened up versus how it felt when you tightened a<br>stock Cummins head bolt. At the time I did this, I was<br>running a B-1 Turbo pushing almost 60lbs. of boost<br>and I am sure that is one of the main reasons I &quot;blew&quot;<br>the headgasket. <br><br>Hope this has helped you out some.<br><br>-------<br>John_P
