does anyone know how much a stock 2T cylinder head needs to be shaved to get 9.8:1 compression coz ive had mine shaved,new pistons and rings and im getting lower comp than a stock 2T. The rings were inserted correctly and its done 1500kms and still no change in comp. Wondering if they gave me a smaller height piston but they fit in nice and snug so i got no idea?
please any thoughts or advice????????????

is it a stock cam? si the intake cam retarded?
valve timing will affect dynamic compression.
did you measure piston height/dish,combustion chamber volume etc when assembled?

oh, and just calculate the shave needed  use compressed head gasket thickness of 0.8mm. it's not that hard
