Thicker Head Gasket?

Hi all.

I've just had 0.002" taken off my replacement block and my refurbished head was skimmed too (yet to find out by how much). Would you recommend that I need a thicker Head Gasket?

Cheers in advance.

I don't know if anybody makes thicker head gasket for the 850

Hi mate, you need someone smarter than me to tell you if that amount of skim would effect the compression on the engine but i would think not, and as Paul say's never heard of them for the 850 but i do know Smithy managed to get a metal one for his 940.

are you sure it was only a "2 thou" skim and not a 0.020" or 20 thou skim
just it seems a very small cut

If you want one these seem to be a good start point

I have a feeling now the Focus tuning market is opening up, we might benefit from a few goodies, but as they use the 2.5 block the head gasket isn't going to help use.

I'm not surprised about the metal gasket for the 940, there is a lot more tuning bits about for the red block.

These guys have made thicker gaskets for me. Not for T5s but I'm sure they could help.

Salut!

I used a triple layer metal gasket on the 850 block designed for the s60r so they do work even though they are not the correct bore size. I then switched to an 83mm bore block and again used the same gasket with a late head. You shouldn't really have a problem as you can fit cams with a lift up to 10mm so a few thou cut to both sections shouldn't be to bad as long as the cuts aren't to excessive and you use a mild lift cam setup. so using a standard gasket should be fine without getting a ferriday item made.

Cheers all, for your replies. I'm picking my block up tomorrow and I can't wait to see it.

Alan. Thanks for your reply. For now, I'll be using standard Cams, so do you think the compression ratio or general clearance will be a problem? I personally don't think so, I'm just cautious after spending so much money so far!:eek:

Thanks again.
