All Aluminum LS1 , but it isn't listed

I agree with ScottJ --I always have(well since th 60's) said that the crank doesn't know what the valve cover says.
Besides that, many of the engines we build these days don't have a single piece of OEM parts in them--the most some of them might have would be a crankshaft dowel, camshaft thrust plate or freeze plugs
