All depends on how confident you are that all the tolerances are correct.
Take it easy for at least 500 miles increasing RPM's each 100 miles and don't idle it for extended periods and vary the RPM's on the highway.
Use this time to make sure everything is 100% before you lay into it.
The Hardness test for an aluminium head is a very simple procedure using a graduated tube with a captive ball in side which is upended on the head surface and the ball is released.
You watch how high the ball bounces in the tube and this according to the graduations will tell you how hard the...
12x1.25mm tap
The Cometics can get away with a less smooth surface finish than the HKS so seem to be the MHG of choice.
I just install the ARP's as per the included instructions.
They burn off the old linings then "bond" the new ones on and radius grind them to size.
Bonding is a high temp gluing procedure and is how they're attached stock.
I got a set bonded up at my local brake place it cost $20>30 from memory.
Unless they're really worn down I wouldn't bother as even to brand new spec they're thin as so look worn out!
I'd use it and will do so on any motor I build from now on!
Very impressed with it the only con to using it is it's sticky shit so EVERYTHING must be spotlessly clean and ready to go before you lay is down on the deck! (You'll find the neighbour kids stuck in it if you're not careful! ;) )
Joel: Good find but it's not new ;)!
I remember these from when I was a kid...... yeah yeah I know Noah used em on the ark I helped build blah blah blah <grins>
CRC/ WD40 /PB Blaster it and let it soak for a few hours then take a large pin punch and making sure you get the direction right for undoing the lock nut place the punch in a notch and give it a whack this "should" shock it loose enough for the wrench to work!
Not really sure what's available in full face for that TQ rating but I'd guess anything that strong will be a puck disc!
I run a twin disc solid centre full face ceramic here and while it can be a little tricky to drive it never slips!
Disc type= smoother progressive engagement more tolerant of being slipped
Puck type= On off capable of holding a good deal more TQ than a full face due to higher force per sq inch of material don't like to be slipped for extended periods .
Soumds like a lot of added complexity for such a simple device, pick a BoV that works the way you want and leave it alone.....(they're NOT a fashion accessory)
