Yes I think the 225s are way too much head for that combo. Now paired with some decent comp, a Super Vic intake, carb, big soild roller, and lots of RPM it may work....although a 205 would be better suited.
If it has a blower it may change things...
I agree with tjm on this one, the 185's are going to be your best bet, not enough motor to take advantage on a 205.
