How can you tell if its an actual Type R head or not?

 

Actual Casting (PR3-X):
* machined intake/exhaust ports from the valve guide to the valve seat
* green paint located by distributor
Internals:
* Dual valvesprings on both intake and exhaust valves
* Intake valve stems neck down to a diameter of 4.6mm before the head

This has been covered dozens of times in the past. If you want more detail than the information provided above, use the search function.

 

ok i have a question.. " I HEARD THAT B16A2 HEAD'S aka em1 si have itr/ctr valves... true or false?

 

false.
the ITR and CTR Valves have a machined neck to reduce weight. B16 Valves are the same as GSR Valves, no swirl machine/polish.

 

even the b16a2? ill have to open it up and check for my self

 

I'll save you some time:



ITR:


94+ GSR:


92-93 GSR:


99-00 SI:

 

thanks

 

You can always count on 92TypeR to give the most explicit/detailed info.

 

Thanks for the help 92typer

 

can i ask about this, is this a type r head with casting of 9/2

 

I believe that means it is a B17A 1992 GS-R head.
