Case 504 3000rpm - porting heads, leave the swirl ramp in intake port or open it right up?

Leave it in, just clean port, you want air speed and swirl

Have you ever ground them off? They seem to be a pretty bad design judging by looking at them, I would think grinding them down would allow a lot mor air in?

Bigger is always better! Big pipe big air big power! Don't forget to do the exhaust side either, what goes in must come out Winking
