Cleaning head bolt holes
Figured I would put this up here because I was searching for different ways that people where cleaning the deck on the block. Anyway, I took a break from the H/C install and got some McDonalds. I was thinking what would be the most efficient way to clean the holes out on the block while I was taking a sip of my soda, and it dawned on me. I took the straw after I was done with the soda and used duct tape to attach it to the end of a mini shop-vac. It worked like a damn charm, makes me feel like a retarded genius, lol. But i mainly put this up here for anyone doing a search.

Take a old head bolt (the long ones) and grind 2 flat sides on it. Chase all the holes out with the bolt and then use brake cleaner to wash everything to the bottom of the hole. Then blow out with compressed air and thread a bolt in to check to make sure they are clean.

First things first. What new head bolts are you going to use? If they are the stock GM units (new) than you can use an old bolt that is cut to clean out the holes. If your going to upgrade to ARP than thats a different story. The ARP bolts are about .005 larger on the OD than the factory units. So when you use the factory bolt to clean out the hole, it will not get everything out.
I am in the process of doing this now.
Buy the way, I used an old bolt first then sprayed some carb cleaner in the hole. Then I blu air in the hole with a rag over it.
