Can I use a E8400 heatsink on a E6850?

[PPete9]

Simple question;

I have an unused E8400 heatsink (due to buying an after-market cooler for my own system) and was wondering can I install this onto a friends E6850 CPU which he has bought which does not come with a CPU cooler?

Thanks in advance for any help offered
