head interchangeability?

[SIMON HOLTBY]

Keith,

New heads are quite cheap in the UK so that is one option. If it was my
car I would remove the head and identify where the problem is. You may get
away with renewing a couple of valves (+stems+seals). On the other hand
pistons ,camshaft may be damaged.
I asked the same question as you about a year ago you may find some
replies in the archives. I think your 4k head will fit but remember the
turbo cars have sodium valves. Look in ETKA for part nos for bare heads
for both cars.
