This winter I plan on sending heads to jay to be cut, putting a 200 ecu and tunner on it and reeds. If I understand correctly this will give me more power on top end correct? I'm already looking at a having to run a spring prop and a summer prop. So I guess I should wait and see if I need to go 2 sizes bigger? Reason I say two diffrent props is I can turn 6000 on my 97 175 efi in 80+ temps and I start fishing when air is in the 40-50's, so I would guess I will be turning more RPM's.
