One method I use that gets you most of the benefit of the retorque is a cold retorque. You can put something like PST sealer made by Loctite I believe or the teflon sealer that ARP sells on the bolts or studs and torque them down on the stand. Wait overnight and then loosen and retorque the next day. If you mark the fasteners you will see they will tighten farther as the gaskets get compressed. This way there isn't really time for the sealer to set up and there isn't any coolant or water there yet either. Permatex also makes a non hardening sealer that I have used on the bolts too. I still retorque hot also, but the above method will get you I would guess 80% of the retorque benefit if you really don't want to do a after heat cycle retorque.

You have to retorque when using aluminum heads its even more important then when using iron I always do. When I put this last motor together it milked my oil I retorqued and no problems since and I am running 15:1 comp. Try retorguing your heads and maybe you can stop the leak. _________________ Take the horse out off the barn and let her RUN BABY RUN!!!!!
