197/200 engine

does the 197/200 engine suffer the same probles as the 172/182 engine

are they the same 2 piece valves as the 172/182, are they a issue if adding high comp piston and rods

any one have issues after modding the engine
 
What issue are you saying the 182 engine has? No ones had any real problems from modding. A a fair few are cammed, mine is supercharged due to be forged soon, and ben on here as throttle boddies.
 
that the head of the two piece valves break apart on the 172/182 engine usually on the exhast side
