my friend has a a fully built b16 head that was tapped onto a b20 block... hes trying to put the head onto his GSR block...what needs to be done to the head so it can be compatiable with the gsr block?

 

it should go right on with no problems
just replace all the necessary gaskets

 

to put that head onto the b20 there should of been a oil hole tapped and plugged on the mating surface of the head,and a fitting for a oil line on the back side of the head behind cylinder four. he will have to unplug the oil hole on the mating surface and remove the adapter four the oil line and plug it. then the head shgould bolt wright on.

 

thanks bro...ill update after it is done hopefully by this weekend
