I was wondering if all the integra b18 non-vtec heads are the same such as the b18a, b18b and b20b/z. The reason i ask is because My b18b motor has a b20 head on it which is marked PR4. I'm guessing the only difference between this b20 head and a b18b ls head is that the cams are different right? I'm getting a b18b block with a b20b head and a set of ls cams. If i install the ls cams in the b20 head, I'll basically just have a stock b18b head right?

 

bump pls...i just need a quick answer if anyone knows it

I think the B18 A and B head is the same, but the B20b/z head is diffrent i think.

 

but the B20 head still says PR4 on it just like the B18. Aren't the cams the only difference?

 

the cams are diffrent, i think the valves are diffrent, if i get this correct you want to put B18 a/b cams into a B20 head? The Lift and Duration of the B20 Cams opposed to the B18 cams is gonna be diffrent, the valves may be diffrent, and i'm not sure if the cam seal for B18 a/b cmas will work on a B20 head. Maybe there is something i am missing, but i don't think it will work
