Engine tech magnum heads

Thank you for the reply. I figured they'd be nothing special but trying to determine if they are any worse than the China engine quest/ jegs/promaxx/speedmaster etc. Sounds like they're all about the same.
Yep. Not a bad replacement head. Not as prone to cracking than the oem heads I heard. They had better be cheap if you are building them from scratch. Valves, springs, retainers, keepers, and seals can add up$$$ The bare heads wouldn't be bad if you could reuse partsfrom your old Magnum heads.
