I have heard it works. I have done the swap many times but I always machined the combustion chamber to match the cylinder. If you want to raise the compression beyond 8.5:1, I think you have to. I think the 8.2:1 pistons are 8.5:1 pistons with the tops lobbed off. The stock 3.36:1 FD ratio seems mighty short with the extra 200cc's. Personally, I think a 3.2:1 would be about perfect.
