Things you should know about EQ Cylinder Heads

• Manufactured in Queensland, Australia by Toowoomba Metal Technologies.
   

• Newly designed to be much more efficient than previous versions, and are not
       allowed to be cast until flow numbers and Dyno numbers exceed previously
       PUBLISHED numbers, averaging 10 - 15 CFM greater than the other manufactures.
   

• Cast at an ISO 9001 facility where one head from the beginning of each run is
       digitally checked for all tolerances, and each head is checked prior to being
       shipped to ensure EQ’s number one concern, maximum quality. Gone are the days
       of “if it looks like a cylinder head, stick it in a box”.
   

• Manufactured with a .4375 thick head deck, enabling better heat transfer, and
       allowing for a better machining platform for decking.
    

• EQ is the only company to manufacture a LOW RAIL valve cover. Our early GM head
       has a machined valve cover rail that enables the installer to run the head in an early
       GM vehicle where valve cover clearance is an issue.
   

• EQ uses only phosphorous bronze guides in the performance head line. 
   

• Using a DURA BOND 30000 series exhaust seat in both the stock replacement
       and the performance cylinder heads.
   

• A TRUE Vortec cylinder head! Unlike the competition’s cylinder head, where a late
       model bolt pattern is applied to an early head, the EQ Vortec uses the latest in
       Vortec technology in our combustion chamber. End Result? More power.
   

• Priced competitively to all other cast iron cylinder heads.
   

• Sold through traditional engine parts distributors and all sales are driven through
       our distributors. We do not sell to your customer, we refer them back to you!
   

• EQ is the only manufacturer of heads in the business offering a full 1 year parts
       and labor warranty on stock replacement applications. (See catalog for warranty
       details).
