Mike, what block? are we talking head bolts/studs? or oil pan rail ,water pump.... if your going into a water jacket I use loctite 565,thread sealant/lubracant.
for heads on an aluminum bock use a head stud if possible (ARP)so your not working the threads and follow the manufactures recommendation for torque values with oil or molly thread lubricants.
every think else use a good nickle based anti seize is best . spark plugs in aluminum heads a little dab will do ya.I like to use studs when ever applicable.
Mike heres some good info on anti seize for reading pleasure. good luck .www.antiseize.com/PDFs/how-to-choose-an-antiseize.pdf
if possible this is best.Aluminum block needs to be fitted with STUDS.
Only was to consider using a bolt in an aluminum block, is if the bolt hole has a helicoil in it, that depending on it's location.
Heads are seldom fitted with thread inserts. I have them installed for my bed plate for the rockers. But that was due to offsetting it on the head.Guess I'll dummy up on the heads, since I've never fooled with V8 aluminum heads. Don't the spark plug holes have a steel threaded insert in them? Or, are those threads actually aluminum?
Same deal on the intake bolt locations in the heads...studs sure won't work.
Lol, sorry guys, still got those round motors still bouncing around.
Didn't notice any inserts in the spark plugs holes on my Eddy heads but I like to use studs in as many places as I can. Round motors.....uh, radials? And what's the population of Tom Bean?Guess I'll dummy up on the heads, since I've never fooled with V8 aluminum heads. Don't the spark plug holes have a steel threaded insert in them?

Guess it's just me...cannot picture putting sparky plugs into aluminum threads...must be my warped way of thinkin'! But, admit I've never took a good look at any V8 aluminum heads.Didn't notice any inserts in the spark plugs holes on my Eddy heads but I like to use studs in as many places as I can. Round motors.....uh, radials? And what's the population of Tom Bean?
Yeah, really. Got my own ways.What is a "sparky plug"? Really?
