The 1098 head has a considerably larger chamber ( 26.1 or 28.3 cc depending
on which head, vs 21.4 for the 1275) so the switch might leave you with a
rather anemic compression ratio.  Now, if you are supercharging the engine
there might be some advantage.... Otherwise I would say that it makes no
sense.
