honda head question

what does a p75-2 honda head come stock on? and the pr4-4 comes stock on the 94-96 g3 integra correct?

second question:i put a new head on my block and i tried starting it up and it puked all over the floor. new coolent everywhere…do i need machine work to make sure the two surfaces are exactly the same or will a new head gasket do?

you should only have to machine the head and a new head gaket is a must in my opinion
