Did anyone use Cosworth head gasket?

[bvass]

I blew a head gasket and I am unsure as to which one to use as a replacement. I came across this one - Cosworth Head Gasket (EVO 8 & 9) : JNZ Tuning Has anyone used it?

I am running an evo3 16G with supporting mods (see profile). My head is currently at a machine shop to get pressure tested, measured and resurfaced(if necessary). I was looking into getting the Mitsu MLS gasket but from what I read it seems both my block and head need to have perfectly flat surfaces to seal. I'm planning on running 25 PSI of boost. ARP studs will be installed as well. Which gasket should I go with? Is OEM gasket an option?

First, I thought Cosworth only made Evo HG's. Second, some people swear by fel-pro or stock composite HG's with ARP L19s or A1s. Personally we never really had much of an issue with the Mitsu MLS; we did have an issue with pushing coolant last season, but I'm inclined to think thats from the stretched ARPs (I was surprised too) than the HG having sealing issues. YMMV

I have always run Mitsu MLS's and have never had one go bad up to 550hp.

I use the MLS as well and have never had any issues - even without getting the block decked.

Thanks for the replies guys. I'm going to get the Mitsu MLS head gasket. Can I run the OEM Evo 8 or 9 gasket - Mitsubishi OEM Metal / MLS Head Gasket (Evo) - Modern Automotive Performance or do I need to get a DSM MLS gasket - Mitsubishi Metal / MLS Head Gasket (DSM) - Modern Automotive Performance ?
