Any real reason to get the 12pt vs the 6pt? (stock)

Not really. Not for stock. I assume you can get higher, slightly more accurate torque (for the purists)

Really that is a new one to me.
The only reason I knew was because way back before the ratchet they used breaker bars at they are called today. 12 point were much easier to make contact and turn with the equipment of the day.
As for contact area it is the same.
Now a days when they are use it is usually because it is in a location that is hard to get a start on which equates back to the breaker bar days.

the six point is harder to round off, but, it can be a lot easier to get a wrench on a 12 pt in many cases.....I think it is easier to round a 12 pt, but, maybe that is cause I like to use cheater pipes? :)
Seems like some of the 12 pts are also a bit smaller in diameter, but, that may be my imagination
-
The contact area is the same on them, rounding happens to the same amount on both.

theory says that is true IF one has a really good quality wrench. The Net is full of guys that apparently don't have that quality of wrench

I keep forgetting about all the china stuff that is out there.
Not to say that some of their manufacture is good when QC is done.

they often work on the theory that quality is based upon what is inspected rather than expected. They have the tools, for sure

Indeed, we have some exposure here. It is an ingrained cultural thing, its YOUR job to prove what I sell you isn't good enough.

12pts weigh less.
They'll move your CofG rearward planting the tires harder and put the cars balance closer to 50/50

Hold on a second there Earl are we talking about the same thing here? :atbeer:

I believe the lighter 12pt heads are a little more dramatic on connection rods :) ...
....but then again it takes 16oz to make a pound!
-
I have 2 sets of each (by accident) for iron heads & aluminum heads. The 12 points are lighter but they "appear" to have no meat on them & I would prefer the 6 point myself.
if anyone wants a set of 12 point for either heads I'll give you a good deal! :atbeer:

Just curious are they actually bolts or studs and nuts etc.

Studs I'll bring them on the 16th if you want to see them?
I showed them to another member & he was surprised how little meat seems to be on the nut compared to my 6 point but they are selling lots from what I can tell? That's what you get unless you specify the 6 point.
-
Does it matter since washers are used?
-
I'm sure they work fine but they just seem like they are so light that the 6 point just make me feel better. That's how I learned & I'll "be damned" if I use this Modern Technology! :068:

Damn whippersnapper s and their, jazz music, motor scooters, and fancy bolt heads
-
Are these not good enough?

Is this true?
" They come available with hex heads or reduced wrenching 12-point heads that eliminate the need for valvetrain removal when re-torquing cylinder heads."

When Steve was a whipper snapper his family had One Bolt & they shared it!!
They were just happy to have the One! They didn't need Eight!! :hmm
We only had one pair of shoes when we were kids & us three boys shared them but we were Gratefull to have them at least twice a week walking 15 miles to school in a Blizzard! :rofl:

Mine were twice that price from Summit & the local jobber?
With shipping tax etc $100 each set 6 or 12 point. They are Studs not like those.

Can't see where it would really matter. Pulling the rocker shafts is NOTHING compared to pulling the exhaust manifolds.
I can't even remember if I pulled the shafts when I retorqued (1/2) my head studs.

I'll take some pics of them side by side on Sat (maybe tomorrow)

Here are the pics of them side by side.

looks like my imagination is still on the job!
-
See what I mean! If each nut is 1oz lighter and there's 16 of them that's 1# off the front of the car!!!!
The CoG will practally be over the rear axle!! :P
-
I can shave .00000001 off my ET! :w00t:
-
It'll be almost as good as taking a piss before making a pass
-
They sure are lightweight compared to the 6 point but that's what you get unless you specify otherwise. Altho saving me going to the bathroom before each race just might be worth it! :atbeer: :chin:
