I need a new cylinder head for a 1997 L400 Space Gear (engine = 4G63 SOHC) and can't find one where I live in Lima Peru. This vehicle model was not sold in the US so to import a new head I need to cross reference the engine. Is "4G63 SOHC" all I need to know to order the head? I'd hate to ship the thing down here and not have it fit. Any suggestions on where to get a good rebuilt cylinder head would also be appreciated. Thanks.
The issue is the number of valves. The 2.0L 4G63 and 2.4L 4G64 SOHC up to
1992 have 8 valves with the plugs on the front side. From 93 onwards, the 4G64 SOHC has 16 valves with the plugs in the top. I'd guess that yours is the later 16v type, with the distributor/ignitor on the transmission end of the head.The combustion chamber volume for the 4G64 is probably slightly bigger than the 4G63 unless the 4G64 pistons are dished.
Point is, the 4G64 SOHC 16v head from a 95-99?) Galant will be compatible. If anyone knows if the Galant came with a 4G63, then its exactly the head you need for your SpaceGear. You could likely get away with a 4G64 head will a 1mm reface of the surface.
Don't consider heads from 93 or earlier as these will likely have compatibility problems eg size of studs, position of sensors and other stuff.
Hope this helps.

The cylinder head for your 8 valve 4g63 engine is common to the English version of the Space Cruiser. Ensure that you replace both balance shaft and timing belts correctly at the same time.
