what's up guys? my d16z6 is suffering from a case of blow-by so i'm wanting to replace the engine, but i'm thinking of buying the block and head seperate cause i've seen them pretty cheap on ebay. i've heard that a d16y8 head increases compression adding horsepower and torque. is this true? would it be worth it to find a d16y8 head for the d16z6 block, or should i stick with a z6 head?
