Which head bolts?
 

What should I use for head bolts? I have almost all my parts for my project, going with 243 heads, Thunder Racing cheater cam, TBSS intake and a 90mm TB. This is all going on an 02 2500HD.

ARP's IMO

I would call and get them from SDPC, they helped me get the correct set for my 6.0. Great knowlegeble guys there for sure.

I went with studs.

the GM parts counter will have studs too, there is a post about what they are from.

Arp's for sure, get the reusable ones. You want the ones that are different length.. Ones in 05 up went to 2 all the same size



Edit--- Wrong info at first ;)

another vote for ARP - studs!

please explain...i have a 05+ LQ9 and havent heard anything about redesigned head bolts. does each head use a different length bolt?

When I ordered mine, they told me there were 2 diff part numbers, that I needed the ones with the shorter bolts..

1997-2003 10 long and 5 short

2004 + all 15 bolts are short

I found this out some time ago the hard way, spent some $ on a good set of head bolts for my 03 well because of a little mishap:eyes:I now have an 04 engine in my truck so I am putting the heads back on and I am saying to myself wait a minute these bolts don't look right. This was right around that time where their wasn't much info at all out their yet on it so I had to make some phone calls and see what was going on.
