This service includes modifying both heads, not just one side. You get a full port job, 5 angle valve job, cylinder head inspection, and the heads get hot tanked for a proper cleaning. We offer this service for all UR engines. Regardless of what chassis your engine is out of, we service them all! LS460, LS600h, LC500, LX570, GX460, Land Cruiser, Tundra, Sequoia, etc.
Please keep in mind that your heads will likely require extra work: heads will typically need to be decked, and you may need other parts replaced such as valve guides. We will keep in touch with you during this process and let you know what your setup needs.
You cannot define every possibility in a single description or for all applications, but 'generally' speaking, what we provide with our Street Cylinder Head Refresh package is great for up to 7,000+ RPM, more RPM would be possible with proper optional valve train.
XAT has teamed up with Manley Performance to provide and develop top level valvetrain parts to build with.
In reality, no matter what purpose/intended use of your build, you will benefit! The truth is unless you are building a 1300HP+ drag car, you can pretty much eliminate any serious deep cylinder head porting. You simply do not gain enough volumetric efficiency by hogging out a ton of metal in the heads, unless you are running a silly-high lift custom cam.
If you live outside of the USA, NO PROBLEM! Please contact us for a shipping quote and we will be happy to help you out!
