The 20R head has straight ports, so can flow better than the 22R head, improving high RPM power. The 20R head is a simple bolt-on modification for the pre-1985 block, but also requires the use of the 20R intake manifold, making it almost impossible (there's a lot of matching necessary) to use with the 22R-E EFI system.

In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head(s). Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders.

Gaskets can be produced by punching the required shape out of a sheet of flat, thin material, resulting in a sheet gaskets. Sheet gasket are fast and cheap to produce, and can be produced from a variety of materials, among them fibrous materials and matted graphite (and in the past - compressed asbestos ).
The cylinder head was developed by Yamaha and was built at Toyota's Shimoyama plant alongside the 4A and 2A engines. [23] The reliability and performance of these engines has earned them a fair number of enthusiasts and a fan base as they are a popular choice for an engine swap into other Toyota cars such as the KE70 and KP61.
