Modern Aluminum head question

[rockfla]

No matter the development of new aluminum alloys and modern anti freeze you cannot stop electrolysis/galvanic reaction between dis-similar metals. Then add the anti freeze to the mix and it increases the problem. Tony,NY is on the right track in using Anti Seize compound on the studs and I would use on the face of the nut and the head. If you can find high nickel content anti seize that's even better, it cost more money but better than standard anti seize. You can usually find the high nickel stuff at an industrial supply store for plumbing/underground utility stuff. You could also try MSC or Mc Master Carr if your familiar with them. The problem with anti seize is you cover more of yourself and everything around you than what you need to coat.
