Blueprinting is not something you do yourself. A machinist does it when your engien is rebuilt.

Blueprinting is essentially equalizing everything and machining it to optimum specifications. It usually applies to equalizing the volume of all of the combustion chambers in the cylinder head. Making sure all the installed piston heights are exactly the same, compression cylinder-to-cylinder is identical, etc.

It may also involve match porting the cylinder head with the intake manifold and the exhaust manifolds. The ports on stock castings may not line up perfectly, so you hand grind the ports so they line up perfectly when the engine is assembled.

The theory is that if all of the cylinders are perfectly equal, the engine will be easier to tune and will run better and produce more horsepower.
