Both heavier than stock.
Check with Spears Racing for upgrade parts. He's been most helpful to me over the years.
Budget builds can use even better parts. +4 +5mm over using ZX-6R cylinders and pistons. Buy used on ebay for $20-30. Press out factory cylinders, machine block for ZX-6R cylinders, install pistons, done!
Look up bruce71198's builds. He's gotten double factory power.
