Head Gasket

slader99 · 05-03-2008, 05:41 PM

I appreciate the feed back but I did use factory head bolts and was hoping to get an answer of what I should do.... I cleaned the threads and applied a molybase lube so I am confident that I adeared to the recommendations of the TRSM and hayes manual. From this forums experience, should I cross my fingers or retorque the head?

On a side note, I've heard several people dogging the factory head bolts, what makes the ARP bolts so much superior? Being a mech eng, I am aware that head bolts are made with both the block and head composition in mind. It is critical that the bolt take into account the thermal expansion coefficents of the head and block so that uniform clamping force is applied throughout the temperature spectrum. A head bolt that is suitable for an aluminum block and head would no be suitable for an aluminium head with cast iron block.
