Cracked domes!

[special fx]

This is what I found when I pulled one of my Big Bores apart! Both domes in the cylinder head are cracked and leaking into the cooling chamber (and vice/versa I'm sure!). This was an MRD billet head and the domes are part of the lower casting rather than individual like an ADA head.

I've never seen one crack like this, so I thought I post the "carnage".

Anybody want an MRD paper weight!!!! mfg:

Red arrows point out the cracks.....
