The heads are aluminum with stock exhaust manifolds. I am running a gasket, not the soft one. What is the proper torque for this application? Thanks,

Kevin

this is what afr says on thier web site about aluminum heads
TORQUING:
"We suggest not using a torque wrench on intake and exhaust manifold bolts, accessory bolts, or spark plugs. Inaccurate torque wrench values can easily strip the smaller threads. Just snug up hand tight with a wrench only"
Just use your highly calibrated wrist

i agree. just make it snug, you dont really need to torque bolts that are smaller then a 3/8 bolt (9/16 socket fits on it), it doesnt need to be that tight and you might crack something if you do
