ARP Headbolt Question I have a 2004 Pontiac GTO. I have a set of (243) heads off of an 03 Z06.
ARP's bolts list for 98-03 LS engines, where all but 2 bolts are the same length. For 04 and up it lists a different part number and all of the bolts are the same length.
Which ones do I use? Why the difference? Thanks.

Not necessarily. Some of the 04 goats had blocks with the short two bolts in them. I've seen each case in 04's. You will prob need to removed either the front or back bolt in the center row of head bolts to see if you need to order the 04 and up or 03 and lower.

Some vendors, Summit Racing for example, will let you return unused parts with no questions, no prior authorization, and no restocking fee. So, if you are willing to handle the return shipping cost and pay (temporarily) for the part you can work around the problem.
