Nick's "tuning" consists of keeping the car stock with a well-maintained cooling system.
Any # of things can cause BHG's...plugged radiator, stuck thermostat, bad rad cap, missing fan shroud, erroded water pump, weak fan clutch, sediment, leaks...I think the torque from Toyota was probably fine when all of the components in the cooling system were new, but now that the car is turning 20...we need a little extra insurance, hence the higher torque numbers.

Replaced stock HG with another stock type hg, ARP Studs to 81 ft lbs boost running around 10 psi just upped it to I'm guessing 12-13 psi...wish me luck.

Actually, the correct unit for torque is ft-lbs, because the calculation is T=r*F where r = radius distance between the pivot point and where force is applied (ft) and F is the force applied (lbs). PSF would mean that T = r/F.

That sounds like it is in good condition. Bad luck can happen though. And if the car is not repaired right, because you never know what that person actually did, then you will lose the head gasket again. I don't mean you personally, anybody.
Easy, that composite headgasket is better than many think. That give that it has is intentional. That iron block and aluminum head moves at different rates as you are alluding too. I don't have an upgraded CT, or turbo. Yes, at 58 lb/ft, I think some people have lifted the head off the block on OEM original gaskets. With some loose headbolts from the heat cycles and abuse over the years. My car only has the HKS downpipe, and keeping it under 8 psi is a challenge, but the factory CT works very well there. The air isn't heated up very much at all. So am not running the risk of detonation.
SupraCentral said it best. Although, some people have only walked into the previous owners problems and didn't know it was coming.
No secret sauce here.
I believe lb/ft read; pound-feet is the correct term. While mathematically, there is no difference, it is only in how the force is being applied.
These "stock hg is reliable" threads are like a support group for people who are scared they will get a bhg every time they drive, but they will not admit it, so they want someone to tell them it's going to be ok.
hehehehehe
hehehehehe
Haha...BHG's anonymous...lol...But I'll be the first one to admit that i am afraid of a BHG, even though I did everything right while replacing it (to my knowledge) and took every safety precaution I could...we'll just have to see what happens.
I'm with you there Jonathan!! I feel the same.. Should I install my 60-1 BB? Would it be ok to boost it around 15psi??
I took as much precaution as I knew.. Maybe it will hold up.. I guess we will see...
If not,, Then I will have an excuse for a total rebuild with forged internals. :naughty:

So true. The only time I don't think about it is when I have some jackass in a Honda reving his engine next to me wanting to race. So I'm like come on, let's go. The gasket will hold. LOL.

Hello, my name is Oscar and I have a fears of BHG. Thank you for your support and understanding. LOL.

I blew a stock headgasket recently after rebuilding the head. Head surface looked good. Block surface was kind of pitted in one spot. ARPS torqued to 75 ft-lbs. Well tuned. It lasted about three months of easy use before blowing right where the block deck was questionnable.
I knew I was taking a chance on that block. There are limits to what torquing down on a rough block can accomplish. That's why I am about to rebuild the engine with a MHG.
