Overhaul help please...

I made a thread the other day about my "new to me truck" that's blowing oil. I found out from a mechanic that it needs an in frame rebuild. My question is if the head checks out good after testing should I reuse it or buy a new one? It's a Cat c15 motor.

Thanks in advance.

 

It was determined that it needed an in frame rebuild. I called the dealer and he ordered the in frame kit for me and i pay labor for install and incidentals. I have to pay $350 to have the head checked. If it's good, he suggests I reuse it. If it's bad, he said he might help out on that cost.
I'm thinking even if it checks out good I should replace it. Mechanic told me if I reuse it and it goes later on and starts blowing head gaskets, that's a $950 part and labor hours to install. It may be to my advantage to just do the head while it's already off the truck.

 

Yes, very nice of the owner to help me out. I wasn't able to think straight on where to begin.

 

I don't have much doubt here. You live and learn. I'll extend myself next time and just buy new.
