Hi I have a 200 block with graham goode cosworth racing standard compression 2wd pistons and a 2wd drive head

I understand that a 200 block + 4x4 pistons + 2wd head = lower compres
CAN i BE assured though that the compression would remain standard with using the 2wd pistons, i'm 99% confident in this?

I bought my 2wd pistons and was goign to rebuild my 205 block,, then a bare 200 block came up cheap.


many thanks.. DAVE
