Default 2003 LQ9 with LS3 heads..Which head bolts to use

I'm getting all the parts together to convert my SBC to 2003 LQ9 with LS3 heads & intake, there are 2 types of TTY head bolts, 3 dif lengths ones or 2 dif length ones.

Which ones would be the correct ones to use?

Input from the engine pro's would be appreciated from this LS newbie, tks.

No I don't not yet, engine is coming next week. I was wondering if the length sizes are different because of block or head differences.

WS6store thanks will do, I'm probably gonna talk to you guys about some of your engine kits that I saw on here, bearings, pistons, rings, timing chain sets, billet plugs etc.... Hopefully the Black Friday sales are extended :o
