Some assembly required
Mine came with the intake valve springs not assembled. Most likely a keeper was not fully seated. Not a huge deal, only took a minute to reinstall the spring and keepers. Still a good deal and worked very well. Would buy again.

Good Fit for GY6
Perfect fit, really simple fix to dirty valves .. much easier than lapping valves... !

Cracked. Low quality.
Bought this in April. Finally found time to tinker with the engine on my dune buggy. Replacing my old head which had stripped spark plug thread. After installing the new head I found it is leaking at the base of one of the head bolt bosses. No compression. Also another note, the part had a loose chunk of sand fall out of one of the cavities.. presumably from the casting process.
