With the head almost finished being rebuilt by GC, I need to get myself a new head gasket. Previously I had been using the Spesso with separate fire rings, but it seems this doesn't exist anymore (spoken to the UK agent) so my choices are somewhat limited now. I know there is Cometic, but I can't remember if I read on a different forum that someone had a problem with it and I'd rather not be bitten again by this bloody engine

You don't obviously read coupe chat then linkyNo block or head machining for the fire ring, the Spesso gasket is crush type ring. GC commented that he only needed to take 0.006" off the head to clear the ring marks.

I didnt have problem with Cometic on medium modified 16vt, but have on cosworth engine. Then we deeper inspect in headgasket design. And i will never use cometic again, it simply cannot work on hi-power application(say 500bhp+ on 2ltr 4cyl). But hold more than OEM 16vt gasket, yes.
Also uk deltaparts sells 1.9mm version as stock thickness, which is bit confusing as oem is 1.6-1.7mm (=you will lost little bit of power just by this replacement)

Just for reference, Spesso have started supply of the "rings" gasket" again after a break of a few years, so drop me an email (trevor@nyssa.ltd.uk) when you need one
