Try the Bosch Super 4 plugs, there's a guy on eBay that sells them for about £25 to £30 for a set of eight.
They worked a treat when I used them.

All you need is standard NGK BPR6ES plugs in a Rover V8,petrol or LPG. Decent leads are just as important,genuine LR,Bosch or magnecore are all you need.The clever,expensive plugs are just more expensive,not necessary in a 1950's pushrod v8.

I just took out some irridium lpg plugs and replaced them with standard gapped at .7mm. huge difference, pulls better and smoother!!

I just serviced my 3.9 V8. Was running Bosch super 4 but, couldnt get them this time (well not in time.) Now have NGK's bosch leads, halfords rotor (i know i know)
Runs fine. The only thing with having the halfords rotor is that it will not last as long as a bosch. Standard plugs with correct gap will work fine. But they will probably burn out slightly faster than the special ones. But pound for pound not enough to worry about

when i put the halfords rotor in it made my dizzy cap wobble..
I run NGK's and they are fine.. although with the poor power I am experiencing at the moment I wonder if I need to upgrade my leads and / or reduce my plug gaps..

i use on all the cars i do standard cap leads and rotor replace every 2 years and split fire platinum plugs and it runs perfectly these i change every 6 years without power loss.
have tried magnacore leads and for the cost felt no difference, bosch plugs gave mine a poor idle too

Something that may be relevant for gas users:
Our Zavoli system will always start on petrol, even when hot, and then switch over to gas, almost immediately if hot or as soon as things are up to temperature if cold.
We find that if we start on petrol deliberately, by selecting that rather than gas, and running it for a few miles, it does run better, even after switching to gas.
There is some interaction between the two control systems, the likes of which I have yet to fathom, but I get the feeling that very often a lot of faults could be cured by a good run on petrol, deliberately blocking out the gas side altogether.
We haven't tried any injector cleaner in the petrol yet, and always keep 3/4 tank of petrol at all times.
I read through the 'Hints' and found a lot of it to agree with, although it could do with a bit of an update now, still a good bit of work.
