Hey guys, anyone knows whats the engine block height for the 1984 320i blocks?

i need a set of custom forged pistons for my build. and i need to know if i can raise the piston pin enough.

the setup would be:
m52b28 crank
m54b30 rods (got them off really cheap :) )
731 head
with a 0,2" MLS gasket

block will be bored to 84mm, and i want to keep the CR at 8.5:1 for a turbo build.
my worry is that the dish on piston to lower the CR + raising the pin will result in a fragile piston.

i know i could use my 130mm rods, but i want to have a good rod/stroke ratio.

any advice?
