Just got a few questions i hoped some intelligent lads could offer some insight on.

Going the harrop 1900 over the 2300 if im never going to stroke it is the aboslute best choice, correct?

if i wanted more power before it goes on the dyno i was thinking of doing something with the heads
do you just get work done to your stock heads or do you buy aftermarket ones? what would the cost of either be
and is it worth it for the power gain?

i've got a growler intake now i was told it would help improve power to go with the VCM airbox, is that worth the
extra 500 bucks? wouldn't the growler be much the same if both are an airbox style intake?

Thanks for your time!
