Sorry but I have no easy access to that info. If you have a good engine rebuilder shop that had experience with them, that's where I'd go. Personally I never did much with V4s, let alone go that deep into one. Let me see if I can come up with the name of a place that sell nationally for you to call.
You can try calling Engine Rebuilder Inc. 1-800-884-6351. They deal with Wisconsins. I have gotten several engines from them because they had very good prices, but I never asked them any technical questions, I have a very good local shop for that. That's about all the help I can be.
Dan……thank you for taking the time. I will give them a call.
They were a great help……thanks.
