hey if i bore out my b16 to 84mm do i have to do anything to the combustion chamber on the head? bore it out?

 

i asked this question on HT like 2 days ago and only to get one reply.."not necessary to bored the head but will be nice to have one.."

 

well what did u plan on doing? wouldn't the chamber mess up the head?

 

Did my search. This is what I found, so bump.


Unshrouding the valve by opening up the cumbustion chamber to match the 84mm bore on the block sounds like a good idea, I'm just wondering if anyone has done this or has thoughts on it.
