• 2 AAZ head stud/stretch bolt length's?? by blackdogvan on 15 Feb, 2011 10:52
• Why did the AAZ blocks have 2 different stretch bolt options for length? I'm building another AAZ to Mtdi & this AAZ block has the stud threads starting down an extra 10mm. The same studs as my 1st build are too short!! Listings do show 2 lengths. Any insight? Is there a longer stud ARP part number out there?

  Do you mean WTF?  
  
  I wasn't aware of differing lengths, so I'm of no practical use on this one...
  

  
  Thanks Daizee...
  
  
  I'll post the part number...

• IIRC only the mains differed. On is 65mm long and the other I can't remember.
