Head issues???

[Tazarse]

Hi guys just been tidying up my head and noticed a small crack on the thin wall between the exhaust and inlet valve seat on 2 of the cylinders is this common or does it deem the head unserviceable?

Many thanks in advance - rob

It's a common fault and should be fine.

Oh right awesome even with two of them Cracked ? I just checked the other head I have and that has the same so figured it might be common what issues could it cause does anybody know ?

The cracks can sometimes grow to a point where the whole valve seat is buggered, they usually just stay as they are.

My head has had said crack for going on 6 years to my knowledge and probably done 20k+ miles in that time also and they haven't grown at all

Mines cracked too..... Along with slighty munged from a washer being dropped in lol

When I took my head off they were cracked pretty bad, got the valve seats re worked.
