NOTES:
Early 81-84 22R - 22RE and Late 85-95 22R / 22RE Engine Blocks: Cylinder Heads DO NOT INTERCHANGE without considerable modifications.
For increased timing chain durability, ALL 1981 - 1984 should be converted to a double row timing chain, use oil pump drive and 20R - 1981 22R timing component set. For 1985 - 1995 engines, use timing chain conversion kit.
