Nice heads for a price, they worked for my project, I would buy again!
Refurbing my dad’s 2000 Xterra, and as part of the head gasket job I decided to redo the heads. Quickly found out that a bespoke refit at a local machine shop would be super expensive, so bought these from Allied instead.
Heads were spotless out of the box, all threads were clean, so install was a breeze. Emailed allied to ask if I should take any steps to lubricate before startup, they suggested a half pint of oil poured over each head before installing valve covers.
At startup there was a good bit of valve train noise, which got gradually quieter as it idled. Next startup was perfectly quiet, though, and ran far quieter than it did on the old heads.
I’ve put over a hundred miles on them now, still super quiet! Looking forward to driving these for a long time…
Shipped the old heads back, allied received them and refunded me right away!
Llevo 5 días después de que arme mi carro y hasta ahora todo está trabajando a la perfección no ha fallado nada, la culata quedó bien me encantó la culata limpia con accesorios buenos, cero rayaduras en los árboles de levas planitud al 100%, también quiero agradecer la atención Terrence Alison que fue una persona atenta que me contacto para que le dijera las especificaciones de mi carro para que la culata quedará bien, lo único lo único malo fue el envío la verdad si dura más de lo que dicen pero eso es por parte de Fedex que siempre tardan en envíar artículos, de hay en fuera gracias Allied motor parts, por mi culata, sin duda volvería a comprar con ustedes
Good quality part came ready to install at a good price
The heads was well packaged when arrived. Very well machined.
