Make sure you go with either Norm's or my studs. Both are proven, I've heard/seen of one failure with Norm's but don't know about any more. I simply don't like inserts at all. I just did the HG's on a car from Ohio, it left yesterday morning. The HG's were done twice at Harmon Cadillac. Both heads once, one head twice. One side had the 1st repair timeserts and the other had the 2nd repair timeserts. Guess what? All 5 bolts on the top row; that were in the 2nd repair inserts, let go. There was still enough meat in the block to drill and tap for the studs. The car is running great again. That was the first time I received a hug from one of my customers!
If the 2nd time they try inserts, it fails again, it tells you something. I wish you the best of luck in which ever type of repair you choose.
Oh Taylor, give me a call Monday morning about your TCC issue- I'll need a complete list of your PCM codes. Thanks man.
thank you for the info i was tring to get my car to 97eldo but to far so had to sgo from thereand ettle for this job close to home will call the shop and recommend the studs and see if i can order them from 97eldo and ship them the my mecanic monday morning i will call him at 8am and go from there thanks guys
It's unfair to say Norms are not as good as Jake's studs. It's OK to compare and contrast the differences, but in all accounts you know that it's the aluminum threads in the block that fail and never the insert itself, so if both studs and inserts are the same 5/8X11 thread, just how is it that Jake's is automatically better? I have nothing against his studs, but I have used Norm's exclusively with no failures on over 30 cars, with some that are approaching 2 years and 60,000 miles. Honestly, what's the difference between using Norms inserts with ARP head studs vs Jake's studs? Nothing... The "one piece" stud has as many disadvantages and it does advantages. Jake should know that the gaskets are the weak point. Every car has had terrible head gaskets, the graphite simply gets destroyed. If block porosity is the problem, why is it that all the other bolts in the engine doesn't strip? If someone wanted to spend the extra money on studs, I would highly recommend using a MLS gasket. They are the reason you don't see Fords 4.6 having the same issue. Nearly all new engines use these gaskets, so if people are wanting their car to last 15 years instead of the 10 as it did from the factory, using similar gaskets with a different tension mechanism is not going to permanetly fix the problem. I have repaired many vehicles that all 20 head bolts are 100% tight, so in theory if it were 10 years in the future and those were studs would those gaskets have not failed? I am currently working on a 98 Deville with 78k miles on it and it is a perfect example of that, all bolts snapped really hard upon removal, but had trashed head gaskets. I plan on using Jake's studs for customers who request them so I'm not biased nor have any affiliation with Norm, it's just his inserts are the most cost effective repair method available, and to some saving money is their main concern especially given the information that both are likely to last just as long. Honestly I'm not trying to start any wars here, I just want accurate and honest information given to people. Sorry for the long post.
FWIW I use ARP studs and metal sandwich gaskets in high performance Olds455 boat engines and have never had a failure, and some of those studs wind up in Helicoils because of rusted, wrung-off head bolts where some doofus has tried to drill out the busted bolt threads and missed the center, eating the threads out of half the bolt hole. It is nothing less than a PITA to try and re-center a head bolt hole in the block after someone redrills it off-center. (Helicoils in an iron block are OK, but never in an aluminum block.)
I imagine ARP studs in Norm's inserts OR Jake's studs would equally be the Northstar equivalent of the above.
talk to mecanic this morning and he said he order norm inserts should be there in couple days so just have to wait and hope every thing goes rite.i just want my sls to be fixed so i can enjoy my power that it has.
