How widespread is the Castech head crack?

How widespread is the Castech head crack?

Postby jutgin [OP] » Jan 01 2012, 3:55am

I just wonder how big of a problem this has been since there must be 10's of thousands of these motors out there.
I guess I am just concerned since I just bought one with the 706 casting.
Should I nip it in the bud and go ahead and replace the heads now?

Probably not a very popular subject!
I do have another question that may be easier to answer/talk about.
Are all the 706 heads made by Castech? Or is that why you have to look inside to see the Castech marking?
I know I have the 706 cause I can see it clearly on the outside of the head passenger side.
