Gaskets for siebenrock

[Ileumi]

Hello! My bike has a oli leak on right side. I need renew cylinder head and bottom (O-ring?) gaskets and pushrod tube sealants. Bike is 800CC tuned with 1000cc power kit. Can I use original 1000cc BMW gasket set or buy gaskets from Siebenrock?

I used all OE parts from BMW when I replaced the pushrod tubes on my (previous ) Siebenrock 'special'

OE are fine, the ones Siebenrock supply with their kit come from BMW anyway
