PLEASE HELP "86 Surb, 6.2 torn down, two cracked heads between the valves - bubbles in radiator (yes, #1 and #8)

Can't find proper "86 head casting #14077162.

Will the "86 head Castings # 14077299 ("299") or or 14077901 ("901") interchange with the "162"? They made three different head castings in '86.

Stranded!
