Ok I have chosen the b20b engine block. What head should i go with the b16a or the b18c, or something else?

im using a b16a (second gen) head on mine when i do it.

 

From what I have gathered over the past year, the b16 head flows better than the b18c1 gsr head, and the b18c5 type r head is a basiclly worked over b16 head so it flows better except they are harder to find and cost a bunch more money. I am personally have a 1st gen b16 head with portflow springs and retainers and type r cams.

 

b16 ( I am running a secong gen)

 

maybe price will be your guide?

it seems that the B16 head is without flaw...
