I imagine that after welding and grinding
youd have fragments of ally and grinding wheel everywhere.

Stupid to weld an alloy head in situ and built up,the whole head should be stripped,degreased and pre heated prior to welding.(Not even thinking about letting it cool slowly in a controlled manner after) Esp bearing in mind the poor reputation of the casting in the first place.The material is not too clever and has a lot of impurities in it,any attempt at a weld repair should take all precautions possible.Or it will only end in tears and make yet another clever English engines reputation worse.

Completely agree but that weld looks good enough once all cleaned up to seal against the O ring. I'd be more worried about all the grinding dust thats now sitting in your oilways. What form of welding did you use TIG?

Not that little bit, very little heat to the head at all. And if care is taken no grinding or metal will get into the engine.
Who ever did that did a quality job....... well done

your all welcome to your own thoughts tbh , personaly everything was cleaned out , and depending what you use , u don't end up with grinding dust and remains everywere tbh ,
area was cleaned, ground out and welded , basicly a 30mins to sort and saved a lot of time, effort locating another head,h,gasket bolts and gaskets , saved me a dame fortune seeing what companies charge for new and second hand heads/ engines ,
so im not complaing tbh ,,,
if u guys pref a differnert option ,then go for it ,,,just thought id share a very simple diy fix ...without a hole in your pocket, ps was tig welded with alloy filler , I make plenty of custom other parts

Not good,even as a diy job.Even as simple as the valve stem seals being fried.Its not hard to make a small Tig weld look good,but you cant guarantee freedom from porosity/cracking without a proper strip,degrease,vee out,preheat and weld.Then recut injector hole and pressure test.
You might be lucky and get away with it - good luck if you do.Just don't try charging it out to a customer,it will bit you on the arse and destroy any good reputation you are trying to build.
