...done alot of miscellaneous lately... and until I get the "photo story" put together... (shots of ALL MANNER of stuff I've been doing:biglaugh: ...I thought I'd post a "silly" of me "re-torquing" the head after some hard running since my last head install... BTW, some of the "rear" studs had CLEARLY lost much of their pre-load tension... good thing I CHECKED!)


PS: I don't recommend taking a SELF-PORTRAIT and torquing at the same time... UNLESS you slept at a Holiday In Express and have a Cheerio hat handy...

Looks like you are letting one slip :fart:

Be careful straining like that or that little fart will turn into something messy. You may be the only person alive that can look cool in a cheerios hat,.........nah, not even you could pull that off..............;)

lol niccceee

what hg do u have??


HKS 1.2mm 3 piece steel. I used the ARP moly to torque spec... much lower than stock torque, but more predictable and less thread-flank shear loading.

er... or, SOMETHING like that.

I seem to recall the "re-torquing" instruction... but NOT having re-torqued them after my build. It ran 200-300 miles and I had an electrical short that buggered me for half-a-decade, and several kids came along... just got it running recently, and NOW I remember stuff like the "re-torquing" thing that had slipped my mind! Hope I didn't LIFT the head a little. I might have damaged the gasket "coating" a little. (So far not showing up in the water or boost behavior... but I AM fighting a little heat, me thinks. Probably the 90* weather and the "tuning" runs I'm doing in it.

Oh, yeah... mhg...

...held on by these 12 point nuts with the ARP studs.

The SUPRA makes me COOL... the HAT just hides my "wrenching hair".

Crisp: LOL I never miss doing a retorque no matter what the "experts" say on the subject and so far my findings have been much like yours there are always a few towards the back that have relaxed!

Yeah, I spent nearly 7 years in the fastener industry... automotive OEM supplier, at that as both a manufacturing AND quality engineer... (Toyota, Honda, Nissan, etc...), and I am STILL learning MORE about joint design and fastener technology to this day... interestingly, the range of opinion and engineering behind how fasteners work in different applications is STILL broad and often "argumentative".

...therefore... TORQUE IT!:biglaugh:

ONE thing is pretty certain... a STUD + NUT design is MUCH better at achieving and retaining torque tension than a BOLT in THREADED HOLE design.

(I even changed my CPS BOLT to a STUD + NUT because it was too easy to "strip" if you weren't careful... ask me how I know!:nono: )
