Re: Install head bolts dry? The new TTY head bolts have an anti-sieze compound on the threads.
Many engine builders will tell you to lightly lubricate the “face” of the bolt head that comes into contact with the cylinder head with ARP ‘Lubro-Moly’ or equivalent. Do not put lube on any of the bolt threads. Lubing only the bolt face will make for more accurate torque angle readings, and will let the bolts stretch evenly.
Hope this helps...

Re: Install head bolts dry? Factory block and head bolts have a peculiar coarse thread to them , they come out somewhat hard . This requires extra care cleaning block threads before reassembly, or torque readings will be inaccurate. It is for this reason that i use and reccomend head studs.

Re: Install head bolts dry? I've always run a tap coated with some grease in and out of any holes on the block to insure easy assembly, and also to get any crud out of the hole that mighta snuck in when I wasn't lookin. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Install head bolts dry? For the stock TTY style head bolts its not really nessisary, but for ARP head bolts you will need to lube the bolts and the underside of the head.
With a TTY bolt, lubing the threads is much less of an important thing.
With both types of bolts, clean threads are a good thing to have.

Re: Install head bolts dry? what is the thread of the 11 mm bolts? I am about to do a head swap (puting studs in) but I don't know what the thread is (1.25, 1.5, 1.75, etc....)

It is some wierd size. What we did when we did a H/C job was we ground down the side of one of the old bolts. Then we put a little grease on it and ran it in and out a few times. Did a good job for us since we didn't have the correct tool.
