Sam1647545489 Posted February 23, 2010 Report Share Posted February 23, 2010 I need the torque specs on arp head studs for a 89 5L with aluminum heads with the included moly lube. Some searching got me 65# on the short and 70# on the long ones. Quote Link to comment Share on other sites More sharing options...

Fubar231 Posted February 23, 2010 Report Share Posted February 23, 2010 I use 85 ft lbs on my supra (Aluminum head) and have heard people using up to 100 ft lbs. On the supra forums people vary between 75ft-100ft lbs. Quote Link to comment Share on other sites More sharing options...
Miller Posted February 23, 2010 Report Share Posted February 23, 2010 Start in the middle of the head torquing in stages. First stage 50, second stage 60, third stage 75. It would be like: \ 9 5 1 3 7 / \10 6 2 4 8 / Quote Link to comment Share on other sites More sharing options...
Fubar231 Posted February 23, 2010 Report Share Posted February 23, 2010 Also make sure you do proper heat cycles and check the torque specs after each one. Quote Link to comment Share on other sites More sharing options...
