Antiseize or not with these aluminum heads?...Ive read both on this webpage...also, what should I torque these things down to to that they dont come flying through the hood?????

 

I hear anti-seizing doesn't do much with our aluminum heads. The most secure way just short of getting the new 8-thread head is helicoiling. Check out my thread on it...

 

No anti-seize ... I just use a squirt of WD40 to lube 'em up a tad ...
Makes 'em thread a bit easier methinks ...

 

I've used Anti seize Both times I've changed mine, now I have 9k on it and race it often and never had a problem.

To tell you the truth next time I think I'm gonna go against what everyone says and use a Mild Loc-Tite.
I mean why not, they say not to use Anti-Seize and I do with no problems.

 

I used Lubro-Moly(German), copper-based, anti-seize 15,000 miles ago and, as Denso says, finger-tight plus 1/16th of a turn more. No loosening problems so far.

Loc-tite won't matter with the amount of heat our heads make will it??

Makes 'em unthread a bit easier me thinks.

Same here Danno

how about on a 4.6? how tight should the plugs be? it seems that hand tight plus 1/16 is a bit loose

 

Finger tight plus 1/16 of a turn put all my plugs right on 14lb/ft... which oddly enough is what ngk recommends as well as many other plug vendors for alu head plug torque.

I also used a copper-based anti-seize.

JB Weld or Locite Triple Red

 

LOL.... JB should hold 'em ndare

 

Well that would make plug changes much more interesting

 

True but keep the little bastard from launchin on ya, thats for sure

 

I was told 35LB FT. I think what NGK says(17LB FT) is a little on the light side.

 

On aluminum heads

in the words of Chris Tucker:

HELLLLLLL NO!!!!!

The object is snug the plugs in so they don't get loose and back out, not strip the 4 threads.
