any advice

I got an 88 ranger 2.3 I'm trying to fix Heads cracked 4 plug 2.3s are getting harder to find I can buy a rebuild for 7-8 hundred I can get a new bare head for 400, using that and the parts for the old one I imagine I can have it rebuilt. I'm also looking at alternatives. An 8 plug head from 89...

Hey im new to rts but i currently own a 97 ford ranger xlt. it has about 225000 miles on it and the clutch is going bad..ive went to some mechanics and some have said that it is better to sell than to fix and some have said that it is better to fix than sell seems how the motor still runs strong...
