There is a tab in the casting at either end of the cylinder head casting - these are the limit markers of where the head can be skimmed to.As long as the head hasn't been skimmed down to these, it will be fine. The standard gaskets aren't available in any other thicknesses. I can supply an uprated one, these are 0.1mm thicker than the OEM gasket. ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |

I can vouch for these gaskets, they are excellent build quality, and my 450bhp lump is still happy using it.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

you can get a thicker standard gasket from Peugeot at 1.4mm, unsure if its MLS but it should be at £60!! (standard 1.2mm MLS gasket is £40)there's other gaskets available at 1.35 + 1.45 but they will be fibre not MLS. Peugeot state that 0.2mm is the maximum skim, cylinder head height should be 137mm ± 0.05 ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |
