You need to check what the compression ratio is going to be. Is this going to be a turbo or non-turbo motor?

turbo.....the compression will be a little high but ill comp with dished pistons or thicker head gasket.

I don't have any direct help, but you may want to search ask in the built motor forum on http://forums.nasioc.com
