Not sure, but it's in the service manual along with the tightening sequence.....which is important. You may want to have a read so you dont warp anything.

Does your 470 have a year? Or a serial number? Which manifold?

Sorry, not a good serial number. 1 to many numbers in it. If you don't have a good number, what's the year? Is it actually called a 470 on the motor, or is it a 170, either could be a model number depending on year.
It's easy to get the specs once we know what it is exactly.
