someone will be able to advise on repair - if not you should be able to
put a liner in

i'm sure there are quite a lot of heads in that condition in use

PJ Engineering do VERY VERY good liners for my last KR1-S.

and id happily recommend them if you looking at sleeving a set of cylinders

I've done it with no probs

the inlet doens't look that damaged, and if the exhaust is less than that, I'm pretty sure (it's not very clear how deep the cut is, but doesn't look that deep) with new nicasil they are ok.

if not : Woessner have one oversize piston's

Yep Seen alot worse heads in use. and that rear boost port is damaged at the bottom so it shouldn't have an effect at all. BDK should be able to get it replated for you, and I would polish out all the high spots in the head with some wet and dry and then have another look at it..

A good second hand head can be picked up for less than £50.

If that head causes Det or pre-ignition the cost will be far greater.

Spend a few more pennies and build it properly. Skimp and it will cost you more long term.
