I have a 454 with alum. heads, everyone says to use antiseize on all the bolts.
Ok, what about the accessories brackets?
The manufacturer said to use locktite on all the bolts?
What do you guys with alum heads use on your accessorie bolts,intake,valve covers,ect......most are steel but a few are stainless.
I dont want them to come loose, but I dont want to gaull the threads either?
Thanks T.C.

I just torque them to specs and use lock washers where called for.

Thanks for the reply 66SS:
I am using a March Serp./ribbed pully system w/AC,PS,ALT, so all the brackets are aftermarket.
I am also using Edelbrock Alum. heads,and thats where I am confused.
The March kit said to use locktite on all bolts, I thought you are suposed to use Antiseize on all bolts with alum.? But if I use antiseize the bolts may come loose?
So..What do I do?
T.C.

anti-seize and lock washers and a delicate hand
they wont come loose or strip if done right

I've been using the March Systems serpentine setup on my car for 5 years (aluminum heads/intake). Nothing special is required. I didn't use thread sealer or anti-seize. I do use anti-seize on my spark plug threads though.

You have to be careful with loktite if I'm not mistaken it could be corrosive with aluminum. On our race car motors I just used oil on the head studs and torqued the nuts.

Thanks for the replys:
I was worried about the dissimilar metals causing the problem, Isnt that the reason for antiseize?
Didnt think of the locktight being corrosive.

T.C. The reason I use anti-seize on my plugs is because the threads aren't heli-coiled. It's tough to get the plugs out when the engine is hot and you could pull the threads out if you aren't careful.
