Cylinder Heads
Blueprinting isn't just a bottom-end dynamic. It applies to every aspect of an engine build from top to bottom. What's more, no matter why you're building an engine, including a oncours-original restoration, blue-printing is good common sense. McAfee's blueprinting regiment includes taking the ragged edges off everything, even valvesprings. Each valvespring is massaged to remove rough edges that cause internal friction and power loss. Internal friction is one of the leading causes of excessive heat and power loss. Each source of friction, no matter how small, makes heat and robs power. Add up these sources and the losses mount.
