Porsche Rebuilt Cylinder Heads by Model

 

The failure of your Porsche's cylinder head could be a very costly repair. A new replacement Porsche cylinder head can cost upward of $4000. The rebuilt specialists at Vertex have develop a rebuilt procedure that restores your cylinder head to as good as new for a fraction of the cost of a new cylinder head.
 

Vertex's Porsche Rebuilt Cylinder Head Process:

Each Porsche cylinder head core is disassembled and inspected for broken bolts,stripped thread holes and broken mounting holes, etc.  All cylinder heads go through a three-step cleaning process which includes: 

1) Passing through a high temperature oven. 
2) Professionally bead blasted. 
3) Placed in a non-caustic hot tank. 

The head is then inspected for cracks & pressure tested. Cam bores are checked for spec and honed if needed.  

The machining process includes;

·         Inspect valve guide bores using a dial bore gauge and repair where needed.

·         New OEM German Phosphorous Bronze Valve Guides & Valve Stem Seals are installed

·         All valve seats utilize a three angle process for maximum precision.

·         The valves are inspected for stem and valve face damage and/or wear, as well as straightness. 

·         All valves are hand ground and/or replaced as needed.

·         Thoroughly inspect and test all of the valve springs for proper tension / resistance and replaced as needed.

·         All head surfaces are machined (milled), not ground!

Final cleaning and assembly includes: cleaning all your Porsche cylinder heads in a solvent base tank in which all oil galleries, thread holes, etc. are cleaned.  Anumber of different brushes are used to catch any remaining contaminants.  All cylinder heads are then run through a detergent based hot tank before assembly. All assembly work is done by hand by Professional and Expert Porsche Specialists.
