So I'm looking into either using ARP head bolts or ARP head studs .. but I can't seem to find the head bolt dia and thread pitch .. it's a 35ci block with 38 heads. Just thought I'd ask now so I can order them while I'm at work .
-
It is a metric pattern, I had a link on my old computer
for the fastener sizes. After lunch I will see if I can find
something out.

That's be great , thanks ...
Once I find that out , I'm hoping ARP will have something I could use...
I'm surprised that with all the after market parts available for the vanguard , that there isn't anyone offering them on thier web sites.

So I did find the size .. M8x1.25 x 85.7
So ARP didn't offer a stud , but do have a five pack of 8x1.25x85mm bolts for $37.00 . Part # 661-1013
This will fit my 35ci vanguard with 38ci heads ..
-
Wrong part # .. that was for 80mm long bolts ..
For the 85mm long bolts , it's 771-1018 ( ARP )

Thanks for the info

661-1018 are the ARP M8 x 1.25 x 85 hex black oxide bolts
