Head bolts will get hot enough to soften it. Anti-seize will lubricate head bolt threads, change the torque value, no way to really know how much torque is appropriate I wouldn't, but maybe Dave Kirk will see this thread and chime in, he's the expert. ;-)ok sitting watching vise grip G... and got to thinking.. anti seize on the head bolts near the exhust valve ???
what say you ??
on the manifold thats fine. iam speaking of the head bolts themselfs.Malox ant acid on exhaust manifold hardware as it won't loosen up like never seize.
these are the bolts that go thru the head itself not the pipe for the exhust.To get proper torque spec, Threads should be clean with a light coating of motor oil.. This is how the original torque spec was rated..
i didnt think it was a big issue.. as long as you didnt put half a bottle on them lol.. just a nice thin coat.Thank you Charlie - I appreciate the compliment. Don't know if I qualify for the "expert" title but I always use Anti-Seize on head bolts, head studs and exhaust fitting threads. Provided initial lubrication for accurate torque values and I've never had a problem with removal after many running hours.
I've used it on many other engine Heads. It appeared to help years later as I had to remove again. Air cooled engines... Torque number is not as critical as equal torque among all bolts. Of course you gotta be in the ballparkok sitting watching vise grip G... and got to thinking.. anti seize on the head bolts near the exhust valve ???

its no longer 2 cents. its now 6 cents hahhahah... with prices of things going up lolI usually clean all threads with a thread chaser, Not a Tap, chamfer the top to remove the first thread to avoid pull-out, oil and torque the bolts, then run through 3 heat/cool cycles and check/re-torque as needed. My 0.02, I've built too many K-Series to count and all are still running.
Never use Antiseize on any Head Bolt !I have always used anti-seize on head bolts. Never had an issue. The same torque that would be appropriate for oiled threads would be close enough for anti-seize as well.
