Valves are the same, but springs and retainers are
different. Using stock Buick or Rover valves (pre-76) may
be marginal with unleaded fuel. Consider replacing the
heads and valves with a set from a US Range Rover(87-'95).
Slightly better breathing and less valve recession on no
lead fuels.

Using composition (sandwich type) gaskets is a good idea
on high compression engines as it will bring down the CR
slightly. Use a Range Rover intake gasket (coated type)
and Range Rover neoprene rocker cover gaskets. Be sure to
leave out the bottom row of head bolts and torque the
heads according to post '95 specs (ten bolts per side
only).

The Buick/Rover valves (through '75) come up on Ebay from
time to time, but may still be available locally as Buick
215 '61-'63 parts. Egge Machine may list them as well.
Land Rover dealers offer competitive prices on the later
parts. Ruth can supply all this stuff as Lance points
out. Rovers North and other Land Rover specialists stock
much for the later heads and I've been very satisfied with
Rovers Down South in New Orleans.
Lance, did you have to pay duty on the stuff Ruth sent
you?

Standard advise: Check the cam lobes and lifters for
wear. Replace if not perfect. Replace the timing chain
with a true roller set (Cloyes, Edelbrock, etc.) or else
you will have to do the same work at some point in the
near future, and if you've stripped the front of an NAS
P6B once, you will not look forward to doing it again.
