i would go with a 416 (.80 over) wiseco and a hotcams stg. 2 and rejet.
i had a JE in mine and after a year it had 2 little cracks on the skirt of the intake side. cought that one in time and put a wiseco in her;) goes better with it to.

I don't plan on increasing the cc's I just want a stock bore.

[fastyz85]

go wiseco thats what i'm getting because they are cheaper and have been around forever.

I have run Wiseco in my bikes and have had good luck with them before. However, I also know people running JE who like them also. I think both a good pistons. My next build I am going to try JE. :macho
