What is the diff between the 337 cc ovation cylinder heads and the 339 cc enticer cylinder heads

 

[opsled]

No difference. Same part #'s since 1978. There is a right/left though.

So even though they are marked diff Cc's
There's no diff
Was the diff in engines just the stroke to make diff Cc's

I understood they were the same engine! Just different carb! My book shows the 337 Ovation in 89-99 as a Liquid cooled???? And the338 Ovation LE 89-00 as the same as the 78-88 ET and 81-88 Excel!
