I need to replace the head gasket sooner rather than later as im currently running a copper 1 and it seems that unless you work for NASA theyre pretty hard to get spot on?? suggestions on a good gasket to use?cheers JET40T Link to comment Share on other sites More sharing options...

I had them for an alloy headed 13:1 compressioned Expensive Daewoo 383. Sealed well after a bottle of chemi weld :-D Link to comment Share on other sites More sharing options...

The falcon already has 8.8:1 comp (iirc) in the turbo motor, so anything less will make it a real dog off boost Link to comment Share on other sites More sharing options...

Everything else is stock (working on a budget) and I will probably run up to 20psi but lower the revs.My question is should I run the MLS-R 1.3m/m multi-layer head gasket I was sent by mistake or get the one that is $150 cheaper and only a single layer (not genuine)?I was considering the difference in compression because I am running an NA motor on light boost atm and it goes well and gets good economy.I also don't want it to blow.
