These heads are designed for hardcore road race competition. Here's a link to a thread with details and why it's not suitable for street use:

Wouldn't it be possible to run some 8.5:1 or even 8:1 pistons to off set the higher compression of the new heads? How much does it actually change the compression? Seems like a good idea would be to run the lower compression pistons with the Nismo heads and hope for something in the 9:1 - 9.5:1 range. That is if the Nismo heads are even worth it. Like do they flow better than ported stock heads and what not. I don't know, it sounds like a good idea.
