Wiseco Piston K394F05
I bought these from my engine builder at the end of the year of 2008. He bought them directly from Wiseco. I was wondering if these will also work with the L92 valve. I noticed the new part number is K394X05 and are listed that they would work with the L92 valve. The only difference if the F and X. I see that the X clears the valve but not sure if the F does or does not( Can't remember).Thanks
