For something that gets frequent plug changes (race motors) I haven't seen a need to do it every time, maybe every other or every 3rd set, as a sufficient amount appears to remain on the threads in the heads.

It has a lot of resistance and can cause misfires. They also advised us to ground each head separately to insure proper grounding with aluminum heads. For a race car that get's it's plugs changed often a drop of oil is better.

When I pulled them to put in a fresh set, had lots of it in the plug gasket seat area. Wiped the seat area down and put the new plugs in with just a drop of oil. Misfire was gone. I have one head grounded. Will do the other. Thanks all. Fastest 300

I've used anti-sieze on my heads for 30+ years but all I do is take a paper match or a small screwdriver, dip it and take one swipe down the threads. It doesn't take much as it will spread itself as you screw it in.

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.

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. Last edited by fullmetaljacket; 02/25/14 03:05 PM.

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 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. Last edited by MRMOPAR622; 02/25/14 08:57 PM.
