Yesterday, i was just finished de-chroming the H2 and when i start the truck...i heard a ticking noise...it was coming from the right engine side....opened the hood....low and behold....it's the famous manifold bolt that we're broke off (the last one)

. I thought GM corrected this issues especially on 2008 model. Well, the truck warranty is over and i have to deal with this....questions for you good folks here is....which bolts should i use...updated oem or the fastenal (11115929)....Does ARP makes exhaust manifold bolts for our truck?....or any best bolts suggestions.....so i can fix this problem right the first time.
