Can't find set of cylinder head bolts for '04 LS1 GTO

help my brothers...........

to make a long story short. I'm having to rebuild my engine due to a little too much spring pressure. that ate the cam and lifters and every exhaust valve seal spring. they ended up in the oil pick up screen.

coming back with all Comp Cam components, (same custom grind cam i had), lifters, springs, retainers, pushrods, roller rockers (1:75 )

anyway GM doesn't have P/N for cylinder head bolts, Federal Mogul (Felpro) doesn't make a set, ARP doesn't make a set

Anyone have similar problem ? Solution ?

Thanks

Count SLP out, too

Well, I got my 3000 page Service Manual for the car, so I guess I have bolt specs. and MIGHT be able to get them from some fastener company or cross over to Felpro, but it sure is a PITA.

I mean, if the dealer has to R/R heads for some reason, WTF

One of the guys in our Houston Goat Herd is parts manager at Pontiac dealer and HE can't help, so far

Thanks DEALER

I didn't understand what HRJ was writing me about that the number didn't exist

He's getting some other small parts together, if he can't get the head bolts, I'll come to you for all the stuff

No problem, I hate the way that GM lists everything seperate, they are confusing as hell to look up. Give him those numbers and tell him to order them from warehouse 41, he should get them pretty quick! I don't mind helping out other GTO owners/dealers, whatever gets you taken care of is what matters to me!

I'll drive down there and kick you in the leg if you have those made! I'll get you a set if you want, warehouse 41 is in Roanoke, TX, about 7 miles from my house and 30 miles from my dealership. If I order them tonight they'll be here Thursday! Let me know.....
WRP said that his springs shipped today.... so maybe yours are right behind them.

HRJ wrote that "supplier has landed" their shipment, so I should be seeing them in a day or so, thank God.

As far as springs go, I went with complete CompCam prescription of lifters,pusrods,cam,rockers,springs,retainers because i found out the hard way that they won't warranty their cams if you don't run their lifters that's printed right on their cam cards.

Thanks for replies

I just found this thread on that other site. Looks like it was more than a backorder issue.
