Re: 200cid head mods?
hi, when you say 1980 200 engine , are you referring to an australian alloy head crossflow engine? if so, the heads are the same for the two engines, as are the blocks. so the best power mod you will make is to fit 250(4.1L) crank, rods and pistons and increase the capacity of the engine. fill me in on some more details and i can help you out. these engines have good and easy to get power and torque. cheers
