Yes, I do that myself. But I don't advocate it yet because I don't
have more that ten to fifteen thousand miles on my rebuilt TD engine, so
I don't know how durable the modified pistons are, in the more severe
TD application.
> He uses less deck height than factory specs for reliability.
I don't understand this. Do you mean that he uses a thicker gasket
than specs call for, so that the compression is lower and hence the motor
has longer life? ?

My machine shop was willing to do the same, but I thought better to
apply the expensive cost of the welding and machining to a rebuildable core,
and keep the damaged head for spares.

I assume that your head was low priority, and was only worked on
when there were not more pressing jobs in the shop. If you don't need
the head yesterday, and you can get a discount for waiting a spell to get
your head back, then this is a good way to go. Locally, I've an excellent
machine shop to patronize, which is owned by a perfectionist. Ahhhhhh,
here is where perfectionists shine. He just cannot turn out shoddy work.
Even being a perfectionist myself, I cannot find any fault with his work.
PS to my APB for a TD head for a 1.6 litre diesel is that it must be with
adjustable valves..........I already have two hydraulic valve heads.
