I have been of the understanding that on my 2007 m8 that i can put on the 2010 jugs and heads with no issues other then the exhaust port being bigger which needs the ypipe spacing as the only issue if a person did not also have the ypipe.

But someone told me recently that the 2010 jug will not fit the pre 2010 case...??...i have a 2010 jug and it seemed to fit fine just sliding it over .

Is there an issue with jug height between the two..??..connecting rod lengths..??...will the squish / piston to head be a problem using 2010 and up jugs and head..??

It looks like it should work to me but can anyone verify please..

Yes .
Power valves are wider so you need them. E port studs are a touch
wider spaced so the best is to use a HO Y pipe. The head is up to you ,
HO head is higher comp. Both pistons will work , the HO is lighter.
