Hopefully this will stimulate some debate on the best way. One place
that has a lot of useful info is the RPI Engineering website;

Heads - the quickest/simplest upgrade is to use SD1 heads which will
bolt straight on - these have larger valves and will improve the
breathing. If you use composite head gaskets you will loose some
compression, but you may find that with lower octane unleaded passing
for premium fuel these days that this is no bad thing. However the
composite gaskets do require extra care when tightening the heads down
as the outer bolts can tilt the head on the gasket

If you want to spend a bit more Turner Engineering and RPI in the UK
can supply higher performance heads; both have excellent reputations.
D&D Fabrications in Michigan are US specialist in the GM/Rover engine
and may be able to help.

Cam - the cam from a 3.9l Range Rover engine is a simple upgrade and
should be available from any Land Rover parts department - cams made
after the seventies seem less prone to premature wear, but you still
need to keep up on the oil changes.  While you're changing the cam
replace the timing gears and chain as I bet the chain will have
stretched over the last three and a bit decades

There are specialist aftermarket cam suppliers if you want something a
bit fancier;  Crower have offered cams for the 215/3500 series in the
past as well as lifters
