Default Re: Intake port piston location???

Be VERY careful changing the height of the ports, this controls timing on these engines and can lead to ruined motors. Most people simply grind a small "ramp" in the piston crown to improve flow. MUCH safer. I would counsel against messing with the port size unless you know exactly what you are doing. If you try the ramp. don't grind too far down into the ring lands. Leave a bit of untouched aluminum above the ring groove for strength.
Search porting and high-performance engine mods. I've seen a thread here on this mod somewhere...
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
