head(s) is not permitted. Intake and exhaust manifolds are
free but they must be supported on the original cylinder
head gasket face.

But 5.2.3 reads as follows:
5.2.3 – Cylinder heads may be modified by machining, provided
that the original part remains identifiable. The valve tappet
guides may be fitted with sleeves if not originally. The
cylinder block may be modified by machining :
•
for the modification of the bore or for sleeving if the
original block is not fitted with sleeves.
• Below the horizontal plane passing through the axle of
the crankshaft bearings for the mounting of the dry
sump.
The oil sump is free and may include the crankshaft bearing
caps.
So now, I'm confused!
