Currently only offering machine work for cylinder heads no block work at this time

Tear down & Cleaning: 

• All parts removed
• Visual inspection of casting
• Heads are baked in oven, glass beaded or shot blasted 
• Final inspection, line bore, surface warpage, stripped threads, broken bolts, cracks, valves, seats, guides, camshaft

Pressure Testing: 

• Heads are setup on pressure tester to check for cracks in cooling system (Heads are torn down and cleaned before)

Magnaflux:  

• Cast iron heads can be tested using a magnetic powder to detect cracks (Heads are torn down baked/ shot blasted)

Crack Repair: 

• We use the cold stich method to fix cracks in cast iron/ aluminum heads. (Note Pressure Testing is required before and during the process. Also other machine work like seats may be required depending on where the crack goes in the combustion chamber)

Guide Work:

• Guides are checked for proper clearance,  or replaced if beyond spec 
  

Thread repair:

• All bolt holes are inspected for damaged threads or broken bolts, heil coil or timeserts are used to repair 

Head Straightening:  

• Heads are torn down, mounted to straightening plate and put in oven for 3-4 hours. Valve Job is required after.

O-Ringing/Fire Rings: 

• O-Ringing uses a .041" SST wire pressed into the head it allows for more clamp load around the combustion area composite gasket only
• Fire Rings use a .120" solid SST ring,  the groove is cut in the head typically (most common) or in the block.  In some cases its split between the block and the head.  This method uses a special MLS or Composite Gasket with the fire ring section of the gasket cut out. 
• Recommended for high boost/hp applications or even stock power for added reliability 

Valve Job: 

• Standard 3 angle valve job
• Valves are cleaned, machined and replaced if necessary
• Seats are cut using a 3-angle cutter
• Manual valve lash adjustment can be done at final assembly for an additional $100 ( if applicable)
  

Harden Seats: 

• Seats that are damaged or, machined to many times will need replaced.
• Engine's Pre 1975 that ran on leaded fuel will need new hardened exhaust seats installed to run on unleaded gas
  

Resurfacing: 

• Deck surface of head is machined to give a smooth/true flat surface for proper head gasket seal.
  
• Manifold side is done upon request price depends on setup
• A specified amount to remove off deck surface for higher compression $140 per head for 4 cylinder, V6 Heads, V8 Heads
