b20 compression

[EGLSHB]

how much does the conversion from the B20 head to a B16 head raise the C/R of a b20? like, if i buy 10.5:1 pistons for the B20 (84mm bore) will the smaller combustion chamber of the B16 head raise it much? like to an unsafe level?

and no, I am not fucktard newbie... just haven't found any clear answers on the web...

i think i found the answer elsewhere , but opinions are welcomed

Pistons that give you 10.5:1 compression in a B20B/Z should get you 10.94:1 compression with the B16 head. With stock USDM B20Z pistons and a B16 head, you'll have 9.96:1 compression. Stock USDM B20B pistons with the B16 head will get you 9.10:1 compression.
