    northstar studs

    Im aware of supply issues with a certin company making studs but is anyone else making a set? I took on a head gasket job as a favor for an elderly man with little money and didnt expect parts supply to be an issue. Id rather stud it than inserts but i figured id give it a shot before going with inserts. Any help is greatly appreciated. Sooner the better as the old man rented a car because i said i could get it done in a week.
    Thanks!

    Don't discount inserts and a new set of head bolts OR studs out-of-hand. If you're in a bind, talk to both Norm Huhn at www.huhnsolutions.com and Tim Carroll at CarrollCustomCadillac.

    Yes, studs are the most elegant solution, but again, don't discount a healthy insert job.

    Sub, be kind when you slam me for my reply.....but:

    I think the one major advantage of studs is that they are being mostly pulled when being torqued, while serts seems to have more of a twisting load when used with stock bolts.

    I will admit that I have one concern WRT studs.....there doesn't seem to be the level of engineering in them that was put into the stock bolts....ie, how much do they stretch? How much do the expand and lengthen when heated? Do they keep the ideal clamping load on the head gaskets when they go thru a heat cycle?

    On the issue of cracks after the repair......if you make the hole bigger, the amount of aluminum around the bolt will obviously be less....and leads to a higher chance of cracks.......makes sense to me!

    Not sure why just wanted it i heard so many good things everyone was saying studs are the way to go
    the Block was ordered new from Jake he shipped it to David at PowerTrain Automotive along with the studs
    so i figured id give Jake the business he was really good on the price also
    i am not sure if david even marked up the price on the block at all i think he did the parts at cost i know the block was like 500 is what i paid
    for a brand new never used Northstar Block from an 02 casting

    NS300L inserts will do the job just as well as studs will.
