LB7, LLY, LBZ and LMM CNC Ported Cylinder Heads.

These are CNC Ported in house using the latest in simultaneous 5 axis Cad/Cam technology on our own equipment. We have over 24 years of cylinder head manufacturing and porting experience and have worked with many of the top teams in Nascar and NHRA.

 

Stage 1

(For the budget conscious racer)

Send us your complete cylinder heads and we will perform the following and reassemble with your valves.

Simultaneous 5 axis CNC porting of the valve bowls only and radius of the intake inlet.

Precision 5 angle valve job. We maintain the factory measurement spec from the deck to the valve.

32 New spring cup bases.

32 Chrome Moly retainers, specifically made for SoCal Diesel.

32 New Beehive "Ovate" wire valve springs. We designed these springs specifically for the performance needs of a Duramax. They are made specifically for SoCal Diesel and are not available from anyone else.

32 New Valve stem seals.

Prior to assembly the cylinder head deck surface is given a clean up cut to insure flatness.

$2,200.00  

 

 

Stage 2

(This is currently our maximum effort cylinder head offering) We start with qualified cylinder head cores which are then CNC ported and treated to the following:

Complete simultaneous 5 axis CNC porting of all ports and bowls guarantees repeatability port to port every time. Hand grinding this type of cylinder head and expecting repeatable results is an exercise in futility. You may get one or two good bowls or ports but let's face facts, humans get tired, CNC machines don't!

32 SoCal Diesel Bronze valve guides.

Precision 5 angle valve job. We maintain the factory measurement spec from the deck to the valve.

All 32 Valve seats are removed and oversize seats are installed to accomodate the oversize valves.

32 SoCal Diesel hardned O.D. spring cup bases.

32 SoCal Diesel oversize valves. Stainless Intake and Inconel exhaust.

32 SoCal Diesel Steel retainers.

32 SoCal Diesel Beehive "Ovate" wire valve springs. We designed these springs specifically for the performance needs of a Duramax. They are made specifically for SoCal Diesel and are not available from anyone else.

32 New Valve stem seals.

Prior to assembly the cylinder head deck surface is given a clean up cut to insure flatness.
