Hi, Im looking at buying a 1.3 engine that ive been told has a blown head gasket. The engine is non coilpack and my 1.0l is coilpack so had planned on using the 1.0l head with 1.3 cams and the 1.3 block with crank pistons etc. What im wanting to know is could the extent of damage of the headgasket mean the engine is useless for what I want??
