either way is just as effective, however changing out to different pistons is MUCH MUCH more involved obviously, as you will be removing and rebuilding the whole bottom end.

Low compression pistons are better due to more squish and better sealing. But obviously a head gasket is much easier and less expensive to do, and many people run the head gaskets successfully.
So if you are planning a radical build then you'd be better off with pistons. For a "normal" build the gasket should be fine.

if you go with aftermarket pistons you should also sleeve the block... IIRC, lower CR pistons tend to chew up the fiber-reinforced cylinder walls... I also believe the S2K piston is a "slipper piston" design to work with the walls and oil distribution system.
I could be wrong, though... This was from a conversation I had Mase

If you're serious about this project, your first mod needs to be a beater Going for big enough power that you're going to be concerned with compression ratios on a daily driver, that's 7 years old (an '01 I presume), with a stock differential is not a good idea IMHO. I'm just SC'd with a measely 300hp, if I didn't have a beater I would have done considerably more walking than driving in the past few months.

I'm running 25 psi on 110 octane and very close to 600 whp on just the 3mm HG/ARP headstuds and I haven't had any problems.
