Cylinder Head - New 6.5L Side Mount Turbo Optimizer Head

New genuine AM General - GEP Optimizer ™ 6.5L Cylinder head for Side-Mount Turbo Engines.

This is the latest version of the cylinder head that is interchangeable with GM 6.5L engines as well as current production 6.5L engines. This version of the cylinder head features metallurgy improvements not found in original GM heads as well as small changes.

Head is typically in-stock but can be backordered via store when not in stock to reserve your units before they arrive. Ships to your door via UPS Ground (a bonus as this does not require truck freight).

This is great for engine full rebuilds where you want confidence in a known quality head and don't want to chance some off-shore knock-off head's quality on your work.

This is a top notch quality head with all the right machining tolerances and correct non-magnetic diamond pre-combustion ports specifically for side-mount turbo 6.5L applications ranging from trucks to suvs from 1992-2002.

We've been faced many times with pulling heads on 6.5 engines and performing replacements and asking the question whether the existing engine was "worth" the cost of good heads or cheap knock-off heads. For our own engines, we always opt for the quality unit because it's just not worth the risk of destroying a good short-block over a poorly designed head.
