are there any differences? Im looking for a h22 head, the one i found is from a h22 SH 1997. I would be putting it on a 92 h22a block w/ odb1. Are they identical?

 

They are the same for the most part. You would just transfer all your parts over ie. injectors, TB, etc.

 

SH has slightly bigger cams
not as big as type S though

 

The intake cam on the 4th gen Vtec is Different than the 5th gen, but all 5th gens are the same, and the exhaust of the 4th gen is the same as all of them. I just cross referenced the part numbers.

 

just remember the 92 h22 is closed deck. won't affect anything other than the headgasket you use. (btw use an open deck gasket)

do you have measurements of this or is that something you read over the internet?

I have the engine specs out of the manual. give me a sec and I'll have them posted.

According to that spec sheet the mid heights are slightly larger on both the intake and exhaust cams, but according to part numbers only the intake cam is different and only between the 4th and 5th gens. According to the part numbers all the exhaust cams are the same.

That was according to http://www.slhondaparts.com/

Now according to

https://honda-tech.com/zeromodi...35439

The 5th gens are all the same but the 4th gens intake and exhaust are different

Very Strange

I thought the same thing

 

Looks like I should try and find some SH cams

 

its not such a bad idea. and I'm sure you can find them relatively cheap

 

but since the valve springs are differen't also would that mean you would have to changeyour valve train? or not

 

.0457 and .015 difference on the lobes....wow you could pick up more hp by changing your air filter.....NOT worth a cam swap.....

 

Just for the hell of it I posted a page from the 92-96 helms

I wonder why they mad such a small change? What was the point? They used teh same cams for years and then out of the blue decided to make a tiny change like that?

 

atts robs a bit of power....

 

I think to compensate for the weight difference between the SH and base model? I dunno just a idea.

I suppose, so if someone was to want to use the SH cams they would have to swap the valvetrain also? Might as well just do a complete head swap.

what a pile of re-engineering to do just for a small gain

 

maybe to give an increase in cornering exit speeds???

 

btw, thanks for posting that sheet tactical customs.

 

So now the eternal question,

Why no change in part numbers???

for sure

 

that is kinda weird. You should call honda and reference the part numbers and then ask them about the numbers on the spec sheet

All the info you're looking for is already in the FAQ, under "5th gens - Base vs SH".

The reason the cams are the same part number is for ease of ordering. They have sub sections to the part number when you are ordering them. I worked in the parts department of a Honda dealer for a few montha an they are different.
As well as the factory service manual points out that they are infact different. </TD></TR></TABLE>

Still doesn't make any sence why they didn't change the part number.
