Hey boys and girls,
The red 173 in my Torana is coming out over Christmas for a bit of lovin'.
Just wondering if the head bolts are reusable (assuming they are original or nos) or are they torque to yield? I will eventually change them over, but I don't really want to fork out for a set everytime the head comes off during the build up (which will probably be a few times, for who knows what reason).
Cheers, Brock

yes Brock,
The Bolts are tougher than the block casting, so the block will wear first.
Just look at the thread and if it looks good than it is. Dave I

Cheers Dave,
Honestly, I was probably going to reuse them anyway, doesn't hurt to know though. Couldn't really think of anything worse than getting halfway through this resto and destroying something out of laziness lol.

gday brock,make sure they are really clean too,if not will affect tightening the head down proper,
i usually dab some oil on end as this prevents the bolt from rusting in block

Being Ol' skool, I don't believe in this "mono-torque" black magic.
I've always tensioned the head with oiled head bolts, thread and under the head of the bolt.. Then, warmed the engine up and let it cool overnight.
Then, following the torque sequence of the head bolts, pulled a bolt out, applied thread sealer, then re-torqued to the final torque setting recommended.
Bit of stuffin around but never had an issue and the way it was done back in the days of copper gaskets.

ive never used sealer,i dont really know that much mechanical wise and havnt stuffed around with a motor for years,is it true say back then would tension head and after a while would re tension after so many ks, what happens to the sealer ,would it break its seal,is it in todays world the gaskets only require 1 tension,im talkin years ago ,

Na, drape the shit on then whipe the excess off, where talking about studs here not bolts.

I just dip the bottom in GM let the excess drip a bit and tension them.

Dip the bolt in GM sealing compound, then tension it, I don't re-tension. Haven't had any trouble so far.
