Just completing full restoration 1960 MKII 3.8. Alas head found to be rotten & best shop in SoCal tried valiently to re weld but head is declared junk.
Will a 4.2 head match up (water passages etc)? Having real difficulty located good 3.8 head but several sellers "believe" 4.4 head would match up...if correct wouls ALL 4.2 heads work or perhaps only selected years/head numbers.
Grateful for technical advice
