So my question, is there a difference between the VIII and IX headgaskets? I've read through a bunch of posts about how the OEM one is the best one even for higher power applications. Okay fine I get that. I've read that some people replace the Headgasket when doing Headstuds and some don't. Okay fine I knew that already. But nowhere do I see whether they are the same or not. I've gone to several sites that list the Mitsubishi Headgasket. Some of the are listed as "Evo 8 or 9" and some are listed as just "OEM Headgasket". So which is it?

 

These things also seem to have a crazy range in price. Any ideas of where to go?

 

yes they are the same....and go oem

 

That's great because Lancershop sells the "VIII" cheaper than the "IX". Hahaha....this is good to know.

 

yeah they are retarded if you check they sell ix starters more than viii which are identical they just try to catch people that don't know and rip them a new a$$ hole

 

Wow I'll remember that. It's funny because there are certain things I ordered from the that have been the cheapest around and shipping has always been super fast so I can't completely knock them. Again they are only one of the many internet based sources I use. Gotta love the World Wide Web...haha!!

 

Evo 9 is 5 layer (1.2mm) HG instead of 8's that is 3 layer (0.8mm).
So we have CR difference!
9's HG has 2 holes (for water) less than 8's HG.

 

OOooohhhhhh.......seems we have a discrepancy. Well I'm glad I haven't bought anything yet. Both of you seemed so sure about your answers.

 

Anybody else care to add some input?

 

Umm... JDM and European headgaskets are different for Evos as well...thats all I know.

 

yeah the 9's have different cooling passages then the 8 i thought. atleast i know that's why you can run a 9 leaner then an 8

 

I have them both here and I know for sure !!!!
It depends in what compression Ratio you want!!!!

 

well stock I'm assuming. I'm changing out my headstuds. that's all I want to do. While I'm at it I'm doing cams/springs.

 

Stock CR of evo's is 8.68:1 (Ken Anderson from Cosworth)

 

Anyone care to share some places to get an OEM IX Headgasket?
