As far as dremeling out notches, uuuuuuuuhhhhh, I dunno. I don't know if I'd want to do that myself. Reason being is that the pistons need to be really smooth so no hot spots develop and negatively affect combustion (predetonation, variances in compression per cylinder, etc). Maybe it's easier than I think it is, don't know. Picturing it in my head just doesn't look good . ....but that's just my inexperience....

I can understand the reluctance to try, believe me I was the same way. But when it came down to spending too much money on a set of pistons, or doing it myself and having 3 sets of spare pistons, I wasn't too worried. And if you keep things uniform, always checking and double checking and making a mold of the nothces, things will work out. That's how I've done it and I haven't had a problem. I've even spray 150hp and no problems. I have done quite a bit of research into this and found that the trick is, take your time, make everything uniform and the same, and take off little bits at a time.

Hope that helps.
