Any down sides to using anti-seize on the spark plug threads on aluminum heads?

I have done it in the past... just get it on the threads so it can ground via the compression washer... it still has to ground... the only reason I did it on that engine was the threads in the heads were a bit messed up(I chased them but they were still weird)

I use anti seize on my plugs and also on vehicles at work.As Mr P. said,threads only and you only need a very light coat.

I agree a small bit on the threads.Ive done thousands at work and do it on mine.I even use it on iron heads.I loved customers who thought you could go over 100K and years on a set of factory plugs.I had one that had over 230K on OE set.Came in as a no run.Pulled plugs and most of the plug was gone.That and antisieze makes them come out easy next time.Rocky

They also advised us to ground each head separately to insure proper grounding with aluminum heads. That is one of the most over look things using aluminum heads and with a all aluminum engine it is a must.Its best to ground each head to the same place on the block and run a ground wire from there back to the -Neg on the battery. As for the Anti-Seize I never use it on my Race engines as mentioned above they get changed often,but on Street-Cars that go 1000,000 miles I use just a small amount.

Can't you just do as you say with grounding each head to the block and then grounding the block on both sides to the chassis instead of running a whole other cable to the negative side of the battery? Learning curve here as well. Me and electricity is like a kite and Ben Franklin. I guess he grounded himself as well back then. LOL.

No MSD says thats not good enough,they say ground it to the -neg side of the battery only.
In a frame car thats true... but on a chassis car I just weld a 3/8 stud to each end of the chassis for a ground lead.... on the frame car most of the spot welds have corrosion in them so thats a weak link

I do agree the chassis should be a good ground being you run your Neg off the battery to the chassis.I was having problems a few years back when I put my 1st all aluminum engine in my dragster and thought the chassis was good enough I even had my MSD ground bolted to it instead of the battery.But when I grounded each head to the same spot on the block as well as my MSD ground and run a ground cable to the Neg (which is ground to the chassis)like the MSD tech. said all my problems went away. I can grin about it now but when I was having problems,I did not think it was very funny and the tech. at MSD had a hard time making me believe it had to be that way. PS I like to think that sometimes us Racers are just to smart for our own good....but I guess the Truth be told we are just to Hard-Headed to listen.
