APR Head Studs and Head Torque Information

joshtexican · 06-05-2010, 01:12 AM

So I am trying to torque the heads down on the 7mgte and the ARP head studs still have a little thread over the block.

Is this a major issue?? I knew nothing about this and didnt catch it until now.

Can someone tell me if I can procede with the torqueing?!?

thanks

If you've made sure the holes are clean (no debris inside) and you've chased the threads then you have nothing to worry about. That's the nice thing about studs, unlike head bolts you don't have to worry about the one side where the torque will be read hanging up and causing a false high reading.

Another thing, I put the head on. I tried to see if the nut and the socket I am using will fit the tunnel/hole where the studs are.

Do I have to have the cams off the head to do this job? I am new to this and am having a bit of trouble getting the nut to turn with the socket.

Any help would be greatly appreciated!!

Put head(w/o cams) in line with studs??
Torque the head down(w/o cams)??
Then put cams back on??

I installed mine with a regular socket with a wobble end extension... If you don't already have a GOOD one go buy a Craftsman socket just for this one job... having to dig out the dust from a cheap socket which exploded while torquing down using a cotton swab sucks.

EDIT: I didn't have to pull my cams, just rotate them a few times to get things out of the way.

Thanks cre,

Wow I took the cams off already man. I guess I have to look for instructions on putting them back on.

And yea my socket doesnt fit, so Iam going for one tomorrow in the am. Is it ok to leave the studs like that until tomorrow seeing they have the lube on them?

The studs will be fine..

I hope you pulled the cam's caps in the right order... :s
