here is the pic that that one of the mods wacked last night. this is my stealth head with 500 miles on it. i bet there is lots more heads with the same problem but most guys have just bolted them on and forgot about them.

i guess buying a fake rolex from china and expecting it to be the same quality as a real one is a good comparison to these heads vs a eddie or indy. Chinese knock off vs quality. bottom line is its your money.
