2 AAZ head stud/stretch bolt length's??
« on: February 15, 2011, 10:52:05 am »
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?   ;D

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.
