just got all my parts for new top end and now i want more power,(did not install yet) thinking about sending my cylinders to passion for 12 port, do i need to get the 4mm stroker ,how much more power with the 4mm? i already bought wiesco pistons and bored my cylinders,with 4 mm i will have to get new different pistons,
is the 4mm worth the extra money , i also saw the vito stroker , what is the difference between the hot rod and vito, vitos told me that i can run the pistons i already have , would just the 12 port alone give me alot more gains,
also does anyone know any shops in NEW YORK that does porting?
any help would be appreciated
