Does anyone know where to get metal head gaskets for the 951 or other head gaskets that'll handle 20+ psi of boost???

 

Cometic makes a metal headgasket.

 

We have the Cometic MLS gasket in stock.

 

Performance Developments 949 646 7461, carries the MLS Gaskets, all sizes and some different thickness'es in stock. I think they will have the best selection of anyone as they are a Cometic WD.

 

Last I heard I thought PD went out of business? Anyone know for sure?

 

Not so. I do know they had some phone problems. I tried to call last week and they had found that their phones were disconnected by mistake instead of another number.

Still very much in business. 17 years and counting.

 

I'm using a copper head gasket, and am very happy with it. I also o-ringed the head (standard stainless wire o-orings) -- this way, when the head is torqued, the o-rings embed into the copper to make a very tight seal.

Anyhow, I still have this gasket (I ended up using a thicker one), and would be willing to sell it.

 

p.s. I think metal head gaskets might even be reusable... Group, is this correct?

 

yes

 

As far as Copper ones go, I am not entirely sure about that. MLS head gaskets are reuseable unless they've been damaged of course from something like detonation.

 

Also if you plan on running high boost Cometic has a model called the Fuzion which has gas 'o' rings apparently.

 

wonder if HKS makes headgaskets for these- i had one on my supra and it was nice!

 

Good stuff to know.

 

Nope they don't.

 

So for about 23 psi of boost what would be the recommended thickness??? Also my block already has copper O-rings, would those need to be replaced?
