Torqued studs down on heads. A few studs show more threads, should I.......
I hope I don't get bashed for this being a stupid question. But I torqued my heads down awhile back and yesterday when I was measuring my pushrod length I noticed a few of my studs are showing a few more threads compared to the others. Obviously meaning the nut is turned more on these studs. Yes I did use a torque wrench.
Should I back these few nuts off to even the distance from the top of the stud to the top of the nut. Like the rest are. Thanks for any help.

Yes I have an lt1 rebuild book showing me the exact pattern. I used the new lube that arp has been advertising here lately. Can't remember what it is called.

Yep, did all that. So does anyone see a problem backing off these couple of nuts till the thread count on these specific studs are even with the others?

I'd hate to see you back a stud out... good luck cleaning and successfully resealing it without ******* up the headgasket.

yes definitely! You're not accounting for variations in the casting, possible variance in washer thickness, possible crush of the aluminum from too much torque, etc.

But as the guy said just before you posted all things are not equal. Hope you understand why I thought it was a logical question. My apologies if it wasnt.

My ARPs had some variances too, none too excessive that I can remember but I do recall some having a little more showing then others after tightening.

if you followed proper torque sequence and your wrench went CLICK...dont worry. threads on a stud have nothing to do with the correct torque on a head. you could have a variance in thread depth in the block, etc, etc....unless its an unreasonable amount on one stud and half a nut on another just let it be.
