I have a 1999 skiddo mxz 600, the engine is completely stock except for i will be port and polishing the heads. I need to do a top end rebuild and i was wondering what type of pistons is the best(most durable) for my sled kimpex,spi,weisco,oem. please help

Kimpex are stock cast replacements. Wiseco are forged heavy duty race type slugs. I'd go Wiseco if you can afford it (Approx double of Kimpex).

Have you heard on Cudney pistons? Suppose to be good.
Do a search on them.

P & P the heads?? Do you mean you'll be cutting/polishing the ports (intake/exhaust) on the cylinders? Not much to be done on the head(s). Suggest sticking with OEM or Wiesco's.
