I have used both types of head and found no diff in power or reliablity.

Now that is interesting, what do you know about cracked 200 blocks Mark ?
I know that the later blocks have had core shift and this has made them weak over 92mm or very high power on smaller bores,
My contact at Cosworth says they are looking to make new blocks/head but the time scale is unsure but I would guess over a year.
