Hi Guys Aoa,
This is my first post so bear with me if any thing is not upto the mark here.
So recently I had an incident any my honda's engine got over heated and due to some reasons I had to kept driving until my radiator pipe got brust, so the long story short went to the mechanic and as I wasn’t the 1st owner so the engine head was already faced before and it has pretty rough condition(attached a picture). My mechanic suggested Head Assembly swap by same Japanese engine.
I am not actually sure of it but the mechanic is reliable guy when it comes to advice and it really look bad.
But I never did the swaping and have no idea what to keep in mind while getting one and how much it should actually cost in-between. And what are other key aspects to keep in mind?
Also is swaping this part would also require to change on the vehicle's smart card as well ?
I know these must have been answered previously but I need to know with current ecnomical situation in Pakistan.
Thanks a lot for helping.
Peace
