617 N/A cylinder head vs Turbo cylinder head
617 N/A cylinder head vs Turbo cylinder head
I know on the turbo motors the valves are different from the N/A. But what other things are different just on the bare head?
Is it possible to use a N/A bare cylinder head on a turbo motor?
Anybody done a side by side comparison?

The casting is the same. The cam, exhaust valves and tappets are different. The prechambers and glowplugs depend on the years.
