Dunno which head is best. But L20B heads I think are not good as they have diffferent chamber size than L14/L16.
In Australia the last of the 610 200 B models were factory converted to run on LPG which nobody liked to road test in the Nissan dealership I worked at at the time we considered them a BBQ if you had an accident.
These head castings were bigger L20 B inlet port size normal spec Rectangular exhaust ports unlike the US round exhaust port with the cast in stainless insert But they had the A87 smaller chamber sort of like a late model SSS head very rare but being for gas they also had Nitrided Rockers and standard steel not brass Inlet valve seats.
I believe Nissan Australia sourced these heads from Japan where they were used in both 610's and 810's most likely for the Taxi market in Japan as I doubt they made a separate casting for such low volume in Australia where they did manufacture L series engines.
Maybe Yahoo Auctions in Japan may occasionally see these heads I don't remember the casting number however and information is likely available only in Japanese in that regard
