In case someone else has the same problem here's the solution I've come up with. Use a 24 mm wrench and turn the exhaust cam towards the front of the car just a little, you want the cam to try to turn back. This is going to put tension on the wrench so you can put a chain on the wrench and then wrap that chain around metal support in the front of the engine bay. A couple of bolts can be used to secure the chain to itself. Use a cloth or towel to keep from scratching your car. Then take an 18" breaker bar and a good 17mm socket to the exhaust cam bolt.
Also, if you need to suspend your engine with a 3 point engine support I found that the crossmember engine mounts are the best place to attach the supports. Use a jack to hold the engine in place when the crossmember is being removed and then slip the crossmember/engine bolts back in place. On the back engine support there's a metal guard that keeps dirt from the engine support, I just wrapped a towel around the chain to keep it from damaging the guard.
