I noticed that there is a groove fron the wter jacket to the little hole that goes into the head. Is this normal?



Any info would be great.

No that isnt normal. I would have that head resurfaced.

Well, i am about 99% sure the head is trash then. It would take .050 (at least that) to clean it up. What would cause pitting like this?

That's really ugly. I can't even image what could cause that.

not regularily changing the coolant will do that to an aluminum head. You should change the coolant when it begins to get contaminated but some people let it get full of rust and crap.

Any copper content will eat aluminum fast. So if the water used has a high copper content and the coolant breaks down, thats just one possability or one mineral that will corrode the aluminum.

Thanks for the info. I was off a Junk Yard Donar Motor. The block was good (already check out at the machine shop) head was crap-o-la.

if you need a head i've got a bare one for $80 shipped got pics if need'd pm me if interested.
