How many ft/lbs or what procedure do u use when bolting the lower intake manifold to the heads. I know the sequence in which to tighten the bolts but I have a fear of stripping the heads so I'm wondering how much torque to put on the them to get a good seal and not mess up anything. They are afr 185's if it matters. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>68stanger</b> <br /><small>Member # 7842</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2010,0,24,20,43,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> running AFR 185 and a edelbrock rpm 2 w/1262 intake gaskets. I torque my intake bolts <br />18 ftlbs. seals just fine, no leaks at all. and I NEVER reuse the factory intake bolts, buy new (grade 8 or stainless) for less head aches <img border="0" alt="[patriot]" title="" src="graemlins/patriot.gif" /> <br /><br />im sure you can torque it a bit more but Im a little cautious when I wrench down on aluminum. <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>68stanger</b> <br /><small>Member # 7842</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2010,0,24,22,36,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> make sure the sealing surfaces are clean use brake cleaner and a clean rag. Also don't use gaskets for the ends of the intake (front/rear), use sealer, lay about a 3/8" thick bead. torque in sequence and you should be good. <img border="0" alt="[patriot]" title="" src="graemlins/patriot.gif" /> <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>50 Deep</b> <br /><small>Member # 6216</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2010,0,24,23,30,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Thanks man<br /><br />I'm using some arp intake mani bolts.
