I am looking for information on what size of tap i need to chase the threads on the middle and bottom head bolts? Also the holes are deeper in the block and had read to use a 12 pt socket and elec tape the tap inside of the 12 pt socket?
Take a head bolt to your local Ace Hardware (or other local hardware store) and they have thread determination tools back by the bolt section. Just find the one that the bolt threads into.
I saw for 36.98 ARP sells a thread chaser. I went to lowes and it looks like a 7/16x20.
I'll call the machine shop tomorrow. Read on corvette LS forum that they said to grove a stock head bolt. I assume they say to grove/grind it same as a thread chaser?

Metric, pretty sure its M11 x 2.0 mm. Check Summit Racing.
I’m with James, I’m sure it’s metric. And don’t assume anything, research it. Also, instead of a Corvette forum you should be on something like www.performancetrucks.net or www.ls1howto.com.
Update, taking block to machine shop this evening. My heads are being picked up today.
Crank is removed and pistons. I am getting new cam shaft bearings installed, quoted $60.
Ask them to clean block and hone cylinders while it is there. They are inspecting the rocker arms and push rods.
Is there a way to check the pistons/ wrist pins and connecting rods?
I researched on most reman motors except gm they reuse the pistons and connecting rods. I have read it is best to keep stock pistons/connecting rods and replace the rings?
Any thoughts? I'm not modifying the stock flex motor.
