Hum, more details...what are the other mods done to the car, and was the car tuned properly? Also, what type of dyno was used?

so you put in -2cc pistons? wouldnt that lower your CR from the OEM flat tops?

why pistons at all? was the assembly rebalanced?

You should have milled the heads down to 59cc chambers, ran you a set of .040 cometics and got your compression up across the board. Take advantage of them -2cc piston reliefs.

Mill the heads and run a bigger cam. I still don't see you making 470 though that would be a big jump.....

Even with a bigger cam and more compression I don't see 50rwhp gain even if the tune is total ****........
