B16a head is not the same as the B18 head. I didn;t think the ITR head was the same as a B16 head either.
Correct me if I am wrong

Apparently the b16a and ITR heads are very similar....(from memory just a very mild port and polish is the diff)

turkey rather make passing comment than answer the question

ITR head, is not the same as a B16 head. Cams, valves, valve springs, retainers, combustion chamber (pretty sure the B18 head doesn;t have the triangular bits on the head between cylinders for higher compression).. etc are all different.
I think the rockers are the same.

...was just talking about the head....not all the misc stuff inside it!

ops: .....there goes me posting again!

Think outside the square mate - in this case, what is actually nside the square....

[VTEC16]

using this link, it shows that the b15a and b18c5 heads both have the exact same compression ratio on a given head......obviously dont take this as gospel....but it gives you an indication that they are VERY similar...

...and NO....that site wasnt my inspiration in thinking they were soo similar :P

[McChook]

Let's get complicated - do all all 3 versions of the B18C - type R variant have the same head - The JDM has a higher compression ratio due to pistons, BUT....

They may be simillar, but i still think the B18 head is different. As I said, please prove me wrong, kinda imteresting....

Does it really matter anyway??

the b18c1 as in the VTIR engine is not the same head. Its a fair bit different to the b16a and ITR heads.

The head on a B18C VtiR is more commonly known as a GSR head they use a raised intake port for better flow. The DC2R head is a B16A based head which has a hand finished porting and not just a rough casting.
