Hey everyone i have an 83 engine with stock internals and the stock heads... with this it means i have an 8:4 cr (compresion ratio).. i was wondering if anyone knew what the cc of the chambers are on the stock 83 heads??? i also wanted to know what my cr would move to with the afr heads (165 with 58cc chambers)..

 

i think theyre 55c but dont bet money on it

 

i thought they were 68cc but am still unsure... i can't find anything on them just the casting number..
