anyone gonna/have tried this yet???

 

those are only good if your block flexes excesivly due to poor design or poor metal quality but luckily the nissan blocks seem pretty stought, if they people were blowing stock head gaskets left and right it might be worth a try

 

ahhh i see, i jsut thought since out engines are also have free standing cycliners, but you make a good point
