Telling the ITR cylinder head apart from the 1st gen b16
I have the intake manifold and exhaust header off right now. If i took some pics would that be enough to tell? They are pretty smooth and look like they are pretty open.
I know about the green paint, there was a bit there, but i scraped it off when i was washing the motor (didnt know what it was for at the time). But i dont know if that was just put on there.
Cam gears say Pr3 on them which is b16 but they probably use the same cam gears.
I was told that the stamps on the front above the exhaust ports tell the year it was made, mine says 9/8 for the 1st one. So im assuming its a 1998 if thats with it means. I dont think they make the 1st gen b16 cylinder heads anymore, or in 1998 wasnt it just a Crx SIr thing?
I know the cams have different markings, i can take my valve cover off but i dont really want to start unbolting the cams and such, can you tell without unbolting the cams?
Anyhelp?

the cam spray bars should be machined , not cast. thats one easy way.
if it has a 30 right between the valve cover and vtec solenoid , then it is 92-up head. b16a or ITR.

Its got the 30. So its ITR.
They guy said he had a 1st gen b16 engine, then he traded the bottom end for a b18c1, then he got a ITR cylinder head and re-used his intake mani and Tb and dizzy and stuff. So i was thinking he could have just said he got a ITR cylinder head.
But since its got the 30, it cant be a 1st gen b16 cylinder head.
I still wouldnt mind knowing forsure though, what was that about the cams?

I personally have seen itr heads with pr3-3's.
ITR's didnt get a special casting, i dont nor have talked to anyone who knows why some cylinder heads have pr3-3 and some pr3-4

Does anyone know what these numbers mean?
I was told the first one indicates the year the casting was produced.

Ill take out the intake cam tonight and look at the grooves. Which side is the intake? Is it the side where the Vtec thing is on, or the distributor.

If its any thing like an LS head the cam caps have a letter and numbers (ex: E1-E6 and I1-I6 i believe) which ever side says I is the intake side.

im thinking that all it means is what casting line it came off of
ive seen PR3-1,2,3,4
4 different casting lines that they made b16 heads on.

This is a relif.
I was sure that pr3-3 ment nothing except the casting line but when people started saying pr3-4 was ITR's then i got worried because mines a pr3-3.
Anyone have any info on how to remove cams?

removing cams is rather easy
remove cam rails
remove cam caps
remove cams...
its a fairly straight foward matter.

My '00 JDM ITR head is PR3-3 and my '97 USDM ITR head is PR3-2. The casting number has NO relevence to MAKE MODEL OR YEAR, it simply is a casting production stamp...anyways, b16/b17/ITR heads are all from the same cast.

see all above, only numbers that matter are the little number circle thingies (these tell you the date the head was cast, giving a little inference to what the head is)
