Importance of matching numbers?, Chassis, engine, and transaxle zerial numbers Options

[rtmchale2]

I'm curious to get the 914 communities thoughts on how important to resell value it is to keep chassis, engine, and transaxle numbers matching as the car rolled off the factory line. I purchased a project 1973 914, back story suggests all numbers are matching. Current engine is a 1.7L, if I had a chance I would consider putting in a 2.0L, but only if that does decrease value on factory restoration project.

I gather from going through the forums that in doing a factory restoration project, that the project will have better value at the end in sticking with factory options for the car as close as possible. Or is that all just made up and at the end of the day the quality of the restoration will have a bigger impact to future value?

Curious to get the communities thoughts on this.
