Yes

How many? All of them? If not, which ones?

 

[Schurkey]

That info should be in the service manual.

All of them is what I recall. On aftermarket blocks, some do not.

I've been on here for awhile and had never seen a 96+ service manual. I went looking, and no wonder... the thread title is a little misleading now. I had seen this thread dozens of times, but never even clicked on it due to the "88-95" title.

For anyone who did the same, service manuals for 96+ are in here also: https://www.gmt400.com/threads/88-95-service-manuals.43575/

How many? All of them? If not, which ones?

All of them. The stock ACDelco head bolt kit comes with thread sealant on all the bolts. I also applied a bit extra on mine before installation just to make sure.

Don't have one currently. Kinda winging this.

@axisT6 , and anyone else interested, this is the big block builders book I got some time ago.

 

[Papablunt]

@Mangonesailor Nice score. Hard to find that one for a reasonable price.

if your local library participates in the WorldCat innerlibrary Loan program, you might be able to checkout those books if another library that has them participates. I was able to checkout the Mike Mavrigian books: How to rebuild big-block Chevy engines : 1991-2000 Gen V & Gen VI & Rebuilding Gen V Gen VI big-block Chevy engines : how to rebuild Generation V (1991-1995) and Generation VI (1996-present) engines to stock specification
