    Is the 3RZ cyl head prone to cracking? Mine's cracked, and the engine was never overheated.

    And, is there an aftermarket 3RZ cyl head? The shop I'm working with says $650 for a bare aftermarket head that's supposed to be better.

    Thanks,
    Kurt

    I havent heard of them craking. Maybe once in a while. But I dont think its an epidemic. Check out LCE for parts, or a complete head. :)

    Paradise Racing can probably also get you some good parts.

    the 3RZ's are not typically prone to problems like this.
