head studs? Whats the best?

Whats the best head stud to get for a 6bolt? my arp's arent cutting it

I would try to figure out why its happening first, headstuds should not be an answer to remedy blowing headgaskets unless you have ALOT of power.

A. You have alot of power

B. You did not prep the head/block correctly

C. You are knocking alot for whatever reason

D. Headstuds were installed/torqued wrong

E. Headgasket installed wrong

F. Overheating and are not aware of it

Anyone else care to add to the list?

The best thing to do is figure out why its happening, but if you choose to skip this vital step then L19's paired with Fel Pro Permatorque headgasket seems to be the new trend as s working very well for many.

Best headstuds out there are A1's. Shep, Rau and others use them. But, they are quite expensive-I paid 200 for mine, but usually they cost around 600-660 a set. Also, they don't prevent things from happening..Rau blew out his headgasket on the friday evening, weekend of the MCSO, and I've never seen soo much damage to the studs or nuts till then. All they do is clamp the head down to the block..that's it. So, you gotta look at what happened..perhaps a better hg? keep in mind DSM's will push a little coolant under boost..

ARPs aren't the problem here. Good post from blacknova, pretty much sums it up.

dont have a blown headgasket. Under boost it does push coolant tho. Just trying to see whats better out there for studs. I guess they have different strength ratings, and wont strech as much as other.

just wondering whats the best out there or what there is i guess.

As far as I know, best to lest-best:
A1
ARP L19
ARP standard
Stock

Where did you get the information that dsm's will push coolant? Pushing coolant should not be an acceptable thing.

Why is it pushing coolant if you dont have a blown headgasket?

If you are worried about headstuds then whats going through your mind is our head raised, and if your head raised, your headgaskets is blown and is the culprit of pushing coolant.

Shane told me its rather common on dsm's he's seen on the dyno.

I have also heard its common from others.. and it says it here too..

Because of the many head lifting issues on 4G63 blocks running in excess of 35+ PSI, a stronger stud needed to be manufactured to meet the demands of today's top engine builders and racers alike.
