Just wanted everybody and their mothers to know, I'm offering a service of ported/polished rebuilt heads (mainly KA24DE) at considerably low prices to get some of our fellow 240 lovers back on their feet! I am able to rebuild other heads just ask


Just to compare and see what kind of deal you're really looking at...
Standard ka head rebuild at machine shop: $350-450
Full port and polish Job on aluminium 4 cylinder: $200-400

MY PRICES:
$320 for standard rebuild
$450 for rebuild with P&P
+$60 for 3 angle competition Valve job
or
+$40 for 2 angle Valve job (Recommended)
+$150 for Cryogenic Treatment (Highly recommended)(at professional cryogenic facility)

Your head will be:
Jet washed
Decked(resurfaced)
Mildly ported and polished
**+$30 for turbo porting (significantly larger)**
Port/Gasket matched
Carbon removed on valves
Valves polished to high shine
New Valve seals
And all that other cool stuff

There will be a mandatory/additional 55$ core charge until I have received a good rebuildable head.
-- 55$ to reserve a Head *the core charge will be waved if you bring me your own head to rebuild*

most of you guys will need shipping so it'll be around $45

MORE INFO ON CRYOGENIC TREATMENT:

I am now offering an amazing deal on Cryogenically Treated KA24DE Heads.
Heads will be treated at a professional facility that specializes in this process. Your head will be much stronger, wear resistant and much more reliable. Perfect for daily drivers and even better for Racing applications.
What will be treated?:
Entire Head, Valves, cam buckets, valve stems, valve seats & cam caps(bearings)
What will not be treated?:
Cams, springs and retainers

All Cryogenically treated heads will be a flat rate $150 extra to any head i build (stock or P&P)


Below is a list of the benefits of this treatment:

Cryogenic treatment is an extension of the heat-treating process that further enhances metals in the following ways:

Relieves residual stresses
Promotes a more uniform micro-structure
Precipitates eta-carbides in steels for increased resistance to wear
Cryo treated metals enjoy the following benefits:

Longer life due to reduced wear
Less failures due to cracking that result from the propagation of stress lines
Improved thermal properties
Better electrical properties with reduced electrical resistance
Reduced coefficient of friction on polished metals
Less creep & walk, and improved flatness for critical tolerance parts
Easier machining, polishing and grinding for better edges and finishes
Cryo treating can make a major contribution to solving these problems:

High abrasive wear in cutting tools, molds, dies, brake rotors, gears, engine components, etc.
High corrosive wear in chemical, food, and oil equipment applications.
High erosive wear from, water, slurries and other abrasive grit carriers.
Distortions induced by design, forming, machining or environment.
Stress relief in complex tools, components, and welds.
Stress relief cracking of weld zones.
Surface finishing in any application where long life is needed.
Stabilization in parts and components as a result of stresses.
Machinability in aluminum and copper parts.
Electrode life in copper resistance welding electrodes

*I will not disclose any info on how I make this service possible so please do not ask*
