If you need to replace the cylinder heads on your waterboxer, you've come to the right place. We offer two excellent options for you: As-delivered from AMC, “right out of the box” fully assembled by AMC for the best price you will find anywhere, or the same great AMC casting built by GoWesty - for no more than some retailers get for the “out of the box” AMC head.
Fits: All 1983-91 waterboxers. Sold individually. Two required per engine.
Please make your selection in the drop-down menu:
• NEW AMC complete cylinder head assembly, as delivered from Spain*, or...
• NEW AMC complete cylinder head assembly, custom-built by GoWesty
*One can purchase an AMC cylinder head for a waterboxer from any number of parts suppliers, but buyer beware. The Spanish AMC casting is the best there is, but a complete AMC cylinder head assembly is not as good as it can be right out of the box. If you are going to spend your hard earned money on new cylinder heads, we highly recommend you go the extra mile and select our GoWesty-built heads.
We purchase AMC cylinder heads directly from the source in bulk, both as complete assemblies (ready to bolt on) and bare (just the castings with guides and seats installed, no other parts). The complete AMC-built heads we sell are no different than what you can get anywhere else, except for the price—we buy directly from AMC, so we've got everyone beat there! But for all GoWesty-built engines, we use the bare AMC casting and build them up ourselves to the higher standards we require for use on our engines. The GoWesty-built AMC head gets our own parts for final assembly, and we do some extra work.
We smooth the intake and exhaust ports just past the valve seats for better air flow, perform a super quality three-angle valve job, and install brand-new OEM-quality intake and intake and exhaust valves. What we end up with is a cylinder head that is better than the AMC-built cylinder head assembly, and miles better than the original Volkswagen example in all regards.
It is said "You get what you pay for," but that is not always the case. It is simply a crime that most retailers sell the same AMC-built cylinder heads straight out of the box for the same, or an even higher price than we sell our GoWesty-built heads! Nobody knows more about the waterboxer, and our experience represents true added value, making buying a GoWesty AMC cylinder head money very well spent.
Bottom line: you can get a regular out-of-the box AMC head at GoWesty for a l-ower price than anywhere else, guaranteed and in some cases, even our GoWesty-built AMC head for less than what some places get for the regular ol’ out-of-the box AMC head!
Do it right, do it once: cry once!
