Hi guys just wanting to canvas the forum to see what the census is on replacing your cylinder head. I have done 4 of these over ten years on my duel fuel gq tb42. I am now converting it to a td42 with an aftermarket turbo. The motor is currently being rebuilt and the engine builder is unsure whether to go gen nissan or aftermarket head. I have had two gen heads and they have always cracked between 5 and 6 even with the mod in the rear of the head to get rid of the air pocket. I have not had a good run with the gen nissan ones. Does anyone know a good quality aftermarket head manufacturer for TD42, i am in outer east surburbs yarra valley in Vic. Any help is appreciated :)
