I installed a Buschur head over a year ago. Runs great but my head gasket is seeping oil. I lost about 1/2 quart over the last 3000 miles. Should I re-torque my ARP head studs? If so, what is the best method to do so? Or should I should leave it alone?

i always re torque mine to 90 ft/lbs after initial startup. let the motor get to its normal operating temp, shut it down, take the valve cover off etc..

heres the sequence...

Do you loosen and then re-torque the studs to 90?

No do not back them off then torque again.. Follow mitsu's torque sequence, and ARP's torque values of 80 ftlbs. torque in 3 even incraments to the 80lbs. When I torque head bolts I will do one sequence wait 15 min. to allow for any air to escape or the torquing compound to settle. I will do that after each torque cycle. I will retorque after 1K miles. that is just my number. torque when head/block are cool.

same problem with my buschur head. I am just getting it back together now, i tried some of that permatex copper spray a gasket. I used it on both mating surfaces as well as both sides of the gasket. Then tq'd to 25-50,100. Hopefully that seals her up
