Aftermarket head gaskets for FA20

[Matt@Cosworth]

hi they should be ready for SEMA and we will offer std (0.78), 1.05mm & 1.45mm

works out as follows:
so stock = 12.5:1
1.05 = 12.1:1
1.45 = 11.6:1

Got the head gaskets in... we'll see if the price makes sense.

Any further update on this? What are the cons to reducing CR with head gaskets?

Cons are limitation due to a fixed Chain length but plenty of slack for adjustment.
Lower compression is designed for forced induction. In the NA platform no benefit.

I'm currently running turbo kit on pump 98. This may be a cost effective way of reducing some compression without going for a full bottom end rebuild. And with the heads out it would also be a good time to upgrade the valve springs which is also fairly cost effective. So yes very interested if this will work

Looking for some head gaskets. Any feedback on Cosworth gaskets? Looks like they were discontinued, but some are still available.

Still looking for feedback on head gaskets. I had them replaced last year with Cometic and it seems I’ve now blown one of those.
