1971 340 Build - Choosing piston rings dilemma

A 71 340 should have 2.02" intake valves... That was the last year for the 2.02" valves...

72 & 73 the 340 got 1.88" intake valves
Ok thanks, I was wondering about that. What a pity. As I said in the last reply, I got the engine for a bargain A$1000 (340 engines are very rare in Aust) and not sure of it's history but I do know this engine came out of a 71 340 Duster. Not sure why he sold it as he had a Duster in his garage. My 73 Rally Challenger has 1968 340 engine with the 2.02 X heads. So I'm happy with this smaller valve engine, I'm not sure when or where I'll be using it yet anyway.
