After a tear down of my 2.0l engine I started the build up to the 2056 big bore upgrade. Having a Bridgeport I started with the (5) 3/8 oil galley plug on the block halves
Drilling a hole in the plugs and a slide hammer to remove the old plugs then started the installation of the new pugs I was able to order from Type 4 store.

ARP bolt stretch:

Following the instructions for messing bolt stretch required a $60.00 to $200.00 bolt stretch dial indicator. I will do my best to user a micrometer for this. peeps just a little better them guessing and generic number. 0.0005 to 0.00055 torque 30 lbs. I also plastigaged the cleansed the rods too.

1) Clean rod ends and mating faceless
2) Remove grease from threaded rod ends
3) Apply arp molly lube rod threads faces, bolts
4) Assemble cap and rod
5) Torque bolts to 15 lbs
6) Losen first bolt and measure base rod boot length. Tighten to to rod stretch is achieved. repeat for other rod bolt

MY results were:
base bolt measure : 1.8640
bolt stretch : 1.8580
difference : 0.00060 @ 28lbs
very close
I used 27 for my final torque and bearing clearance of 0.0015

You torqued and used the stretch gauge?
I've tested VW and Porsche ARP rod fasteners between 25 to 40 lbs and have found that I get the same result with both methods.

996 bolts (Carrillo and stock rods with ARP bolts) are 40 lbs, good thing the torque is accurate as 3 of 6 rods you can't get the stretch gauge on the bolt.
