Magnus A1 Headstuds

[Magnus]

WE have these in stock right now and are offering a special, 300 dollars shipped



They are made to our specific specifications, We have had a special Nut made to clear all different types of valvespring combinations and 1.5 times thicker washer than normal to help distribute the load better.

These Small but significant changes are what we do to make our product better for the end user!

These are not like other studs out on the market claiming to be similar.

This is the Head stud that all the TOP DOGS are running. This is the Stud that holds Brent's head on his motor when he is running down the track at over 50 psi of boost and 199mph!

Here's who's running them!

Brent Rau 1400hp 6.9!
John Shepherd 1200hp 7.7!
Villenueve + Turcotte 1000hp 8.6!
MAGNUS 1000hp 8.7!
Bill Lowe! 1000hp 8.7!

These will not stretch when reused! I have been reusng my same studs for over 4 years! With the old Studs I would have to buy a new set every time I took off the head. This is because the yield strength of that particular stud was of a weaker material and could not take repeated tension so close to its yield point. They would constantly stretch one or two bolts when reusing old sets of studs. We considered these throw away headstuds,

Here are the 2 main reasons to buy this over the regular cheap 100 dollar headstud kit.

1) If you plan on making over 700hp they will help the gasket retain a better seal to the block
2) if you work on your car often and pull your head more than 3 times a year, you will have paid for 3 sets of throwaway headstuds already.

Why not buy the right ones once. The sad realization is this the people who buy these studs have already bought at least 2 sets of regular studs in their life, just do it right and BUY THESE ONCE!!

Well, I'm certainly no John Shepherd or Brent Rau, but in the course of time, we try things. Some good, some bad, some awful.

I've been a very "amateur" DSM mechanic for a long time. In the good old days, a set of standard ARP's were the last set of head studs anyone would ever need. In those days, you were considered a DSM guru if you ran mid-12's with a 20G. Times do change, huh?

Forward this to last year. My buddy Serge (who is a real pro mechanic) and myself are experimenting the growing pains of running a GT42 turbo on methanol and fairly high compression. We blew head gaskets all the time. It had to be the head gasket right? Serge kept telling me that the ARPs would stretch when we re-used them, so we kept buying a new set each time we changed the head gasket.

This year, we went even further in the path of performance with a set of much wilder cams and aluminium rods with the idea to rev to at least 10K rpms. Then we needed better springs to keep the valves from floating.

Problem is that with those newer springs, ARPs washers and nuts wouldn’t clear the springs properly.

So I got a set of those A1 studs from Magnus.

First thing we noticed is that they cleared the springs nicely. No need to fight them to get in.

Second thing we noticed, well, it took a while to notice it, but the gaskets wouldn’t blow anymore. Turns out that the regular ARPs were stretching, even if the tune was correct. We did eventually blew the head gasket once (we had a tuning glitch). Replaced the gasket and torqued the studs again and it ran another dozen of high 8 seconds passes.

Before the SO, we got a little worried about the gasket, so Serge decided to torque the hell out of the studs (don’t try this home) and they never ever started to stretch. We ran 5 8 seconds passes at the SO and the head gasket never failed (last pass was our best trap speed of 171MPH).

So yeah, those A1 studs are the last set of studs you’ll ever need, just like those ARPs were … when running a 20G was dope!

Just got off the phone with the guys at magnus, getting the scoop on these bad boys, if you have duel valvesprings and are worried about clearences with youd headstuds and still want a great stud that wont strech this is what you want. I actually hate ordering parts off the phone but magnus was great to deal with, i wish i went right to them to buy my smim directley. ill update when the motor is in the car at running. The motor there going in a a compleatley built motor corrilo rods, 280 cams, duel valvesprings, new everything, no expence spared.

Thanks Billy!

The phone is actually the way we prefer to do it? Are we old school? Maybe! Cause we've been around for 12 years!

But we prefer to talk to our customers and get them the help they need, and having a two way conversation with someone instead of email you can get alot more accomplished!.

[Billy6411]

haha I just see it as old school, my frineds got a 930 slantnose porsche with a 37r and he built the whole car calling every vender for parts and I always gave him crap askin vendors still do that? but it was defnitley a very plesent and fast experence
