I need some help guys. The cometics gaskets were not shipped with my 418 stroker. I called TS yesterday and talked with someone who said my 60 cometics were a special order. Well that is fine and dandy but we ordered 3 weeks ago. They told me that the order to drop ship from cometics was held off until the block shipped. Now I have no way of getting my motor together! This weekend was my only opportunity and I needed my car running to drive to new Orleans for my half iron man that I signed up for and paid am arm and a leg to compete in

Now I need something to get the car running. Can I use the stock gm ls3 head gaskets? They are the only thing I cam get in such short notice on a Saturday!

 

The bore diameter on the stock gaskets may be too small to use on the 418.

 

I have been using LS7.

Is it NA

It has a tvs1900 and will only be pushing 5 or 6 psi

 

I know SDPC has a 4.085 x .040 gasket in stock but that is too thin for you.

 

Order ls9 head gaskets will be perfect 5 layer
