What head gasket are you using? Alot of people are saying they use cosworth. How much better is a cosworth head gasket than a new oem head gasket? Any help will be appreciated.

 

oem is the way to go

 

+1 on the oem..I had a cosworth one but engine needed to be redone before I could really test it.

 

oem ftw

 

OEM!!!!!!!!!!! Even the race cars use them.

 

Can't go wrong with either one. I myself use a HKS.

 

We have experimented with OE (out to 1100whp), HKS (currently 770), Cometic non-HD, Power Enterprise, etc.

A stopper style gasket is the best design hands down. It takes some looking to find that and for awhile HKS was the only one that offered it in the 2.0L bore. PE does in 87mm stuff.

 

can you use an o-ring with them or is it not needed/bad idea?

 

have you used the fel-pro MLS gasket? why are they all above 200$. thats expensive for a gasket.

 

was that a 3 or 5 layer oem unit?

 

I don't think fel-pro has made one for the 7 bolt yet. But Oem is the way to go.

 

Isnt the cossie gasket pretty thick as well?

 

Cosworth gasket is in fact a stopper type.

 

Oem..

 

The cosworth is a stopper style gasket. I have only found it in the 86mm not the 87mm. It comes in two thicknesses 1.3 or 1.5mm.
