quick question, i have an option to get a b16 head but the combustion chamber has been increased to a 84.5 mm bore, and my block is the stock 84 mm bore. Is this a problem?? i heard the b20 head gasket is 84.5 but still thats not going to be the best combustion chamber, Right? and input would be great

 

no answers??? where the tech guys that hang out in the tech section?

 

I would reccomend getting a regular 81mm B16 head for the quench area........higher compression=more power making ability

 

well i already have a fully built bottom end with JE pistons pumping an amazing 12.5:1 ratio, but i will have to CC the head to get a dome volume to calcuate my final compression ratio. i think i will be okay.
