Which head is better in stock form and which one is better when ported? This will be going on a dart block.

 

i wouldnt say one is better than another, both have their goods...i guarantee that 90% of honda tech will say the b16a head is better because it has the same casting as the type R head.....and availability of the b16 head too..

but both are just as good as each other..and in stock for the b16 only flows a little more than the gsr...so which ever one u find in good condition take it
