Another friend advised me that they were over-torqued, so we cracked them loose & re-torqued them to 85 across the top & 75 across the bottom. it wasn't until we got to the 2nd cylinder head that we realized that some of the washers were also installed upside down (chamfered side was on the bottom)... Anyhow, so we had to go back & do the other head again. The engine was never fired BTW...<br /><br />So, here are the questions, are the ARP head bolts any good after being torqued 3 times, & are the brand new Fel Pro 9333PT1 composite head gaskets gonna be any good if they were over-torqued & then backed off to the proper specs? The heads were never taken off the block once installed, we only loosened up the bolts. <br /><br />I would rather not deal with a head gasket & head bolt issue once the motor is installed, so if they should be replaced, I would like to do so now. But only if necessary...<br /><br />Thanks in advance.<br /> <br /> <small>[ 2014-02-24, 05:31 PM: Message edited by: *EPIK* ]</small> <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>FivePTSlow</b> <br /><small>Member # 7682</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(2014,1,24,17,37,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Many people have said you can reuse head gaskets as long as it wasn't fired, but do u really want to find that out rather than spend the $40 now for new ones? <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>*EPIK*</b> <br /><small>Member # 7481</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(2014,1,24,17,39,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> </font><blockquote><font size="1" face="Verdana, Arial">quote:</font><hr /><font size="2" face="Verdana, Arial">Originally posted by FivePTSlow:<br /><strong> Many people have said you can reuse head gaskets as long as it wasn't fired, but do u really want to find that out rather than spend the $40 now for new ones? </strong></font><hr /></blockquote><font size="2" face="Verdana, Arial">Yup, this is very true...
