expansion
Hi,
I see you have ALuminum heads, they will expand at a different rate than the iron block so you need graphite head gaskets.There is a front orientation to them. Put thread sealer on the short-lower row of head bolts. Torque the head bolts to 70 ft/lbs. Torque the intake bolts to 18 ft lbs, run and let cool and retorque, do not over torque intake, it will leak.
Good luck,,
Perry.
