They are $58 at Nissan.... if they are still available, but nothing really to wear out on them so a used one would be fine. What owner of a 40 year old Datsun uses new parts???

Datsun 4 Cylinder L Engine Head Castings
Jason Gray Information
The following is a list of cylinder head castings and their corresponding chamber shapes. Keep in mind that list is not etched in stone. For example, the A87 casting can be either open or closed chamber design. The only way to tell is to pull the head. To find your casting number, look just below the #1 and #2 spark plugs. The number will be cast right where the head meets the block.
Casting #: A87 Open Or Closed Chamber
It is found on many L-18 and L-20B's. The "domestic" version usually came with open chambers. Many of the "used Japanese import" engines came with the peanut version of this head. Large quantities of these used engines were imported in the 80's, so the peanut version is fairly common. These heads usually have 1.25" intake ports and square exhaust ports. 1.65" intake valves. Exhaust valves can be 1.38" or 1.30"
Casting #: W53 Closed with some exceptions
This head is from the Japanese market. Some of these castings are for factory fuel injected engines and have notches in the intake ports to accommodate injectors. 1.25" intake ports and square exhaust ports. 1.65" intake valves and 1.38" exhaust valves.
Casting #: 219 Part #: 11041-V9182 Closed Chamber
The true SSS head from imported used engines or ordered from the Datsun comp. catalog. Later versions could be ordered from the catalog with a V912 casting. 1.50" intake ports, square exhaust ports. 1.65" intake valves and 1.38" exhaust. These are hard to find. Any of the other closed chamber heads can be "converted' to this design by simply opening up the intake port to 1.50" (if that's desired) Some of these heads are marked "A87" on the side, but have "219" cast at the front of the head, just below the timing chain inspection plate.
Casting #: 210 Part#: 11041-N2202 SV Open rare exceptions
This is the head that came stock on the 510. Tiny 1.125" intake ports, square exhaust ports. 1.50" intake valves and 1.30" exhaust valves. There have been variations reported on the valve sizes. This head is believed to be originally designed for the L-13, and engine never imported to the U.S. I know of one that has the peanut (closed) chamber with 37cc displacement. The earliest versions had more of a "semi-open" chamber design but later examples were the open chamber design. These heads are usually avoided on performance applications.
Casting #: U67 Open
The stock cylinder head for many L-20B's. 1.375" intake ports, square exhaust ports. 1.65" intake and 1.38" exhaust valves.
U60 open Identical to the U67 head, this number has been found on very early L-20B's. It seems to be fairly rare.
Casting #: W58 Part #: 11041-W5880 Open(with rare exceptions
This is the L-20B smog head usually found on '77 and later engines. 1.375" intake ports with ROUND exhaust ports. These exhaust ports have steel liners that help burn off emissions. I know of one of these castings that has closed chambers. These heads don't flow well and are avoided for high-performance applications.

These are my Weber suppliers for decades Peirce Manifolds. Watch their videos and subscribe to their You Tube Channel.
Call Pierce manifolds great people to deal with. Mike Pierce explains the Weber and gives some good info in the following Videos. They know Datsuns/Nissans. By the way these are old videos and prices have gone up over the years.
