question about magnafluxing head

[Anonymous]

Are these heads(E0 in my case) crack prone in any certain area? I borrowed my buddy's magnafluxing equipment and didn't find any cracks in the combustion chambers or deck surface. Any advice is appreciated. Peyton in SE Ohio

These heads (if your talking about 144,170,200,250 heads) are not bad about cracking. If they crack at all it will probably be between the number 3 and 4 cylinders because of the two exhaust valves being there together.
