Andy, Top end damage we dont care about, we can just fit another head (we both carry spares of that sort of thing!), its just if the pistons have had a hard enoguh whack to crush the ringlands thats it an issue.

We're in the hands of the almighty now in terms of what its done, nothing we can do to effect it now

There wasnt a massive amount of noise from it when it happened, so i reckon we will get lucky on it
