Default Replace head bolts?

I have to pull the head to get it worked on. I have been reading around and cant find any solid info on whether I should buy new head bolts for putting my head back on. By searching iv figured out im going to get a OEM replacement head gasket, but im not real sure on these bolts. The motor was rebuilt by IPS a few years ago, but im not sure if they replaced them or not.

quick question too about the head gasket. Is there a place online I can order oem stuff, or is my best bet to go to my local dealership?

if the motor has been rebuilt allready then they prob reused the old headbolts. that would mean theve been set to torque 2x. thats the limit i use mine. once ive used them 2x up to temp then i would buy new ones if it were me. if they replaced yours what ips did the build then they only have 1 so you should be ok. use oem mls gaskets only!

Yes. Replace head bolt only from mitsubish. DO NOT use the Felpro bolts that most others supply. They are only toque to spec bolts. That means you can only torque them 1 time. But the torque instruction require you to torque them twice. No can do with felpro bolts or they will stretch on you. Your local dealer most likely has these bolts for around $8.00 each. That's crazy. Cherryhill get about $3.35 each.

I was also looking into the same thing. I have my heads off now. For the price of the OEM head bolts it makes no sense to not replace them. Its about the same price of fel-pro bolts.

I would only use OEM gaskets. But if you don't want to spend the money, at least get an OEM head gasket.

Si Si Si.

I would only replace them if you find they have stretched, unless you have been battling head seal problems and feel like blaming the bolts this time around.

They may be cheap, but if you replaced everything just because it was cheap, you would throw away a lot of good things and blow a large chunk of money for no gain.

Its not that hard to inspect them. People who HAVE to replace them out of paranoia are just as likely to do things wrong with a new set because they obviously don't trust their install method. New bolts do NOT overcome installation mistakes. I know someone who did 70ft/lb and then did a 90 degree turn with new OEM bolts, and wondered why his head seal was bad. He thought either the block cracked or the bolts were defective and he needed to buy another new set and repeat the same process, or get better bolts.

Thanks for noting this, sometimes you get into the mindset of "It's aftermarket and it's more expensive so it must be better." But really, cutting 250$ off for the entire set could help someone working on a budget.
