code on the head says pr3-2 and i would like to know what head this is.

b16a,b16b i really dont know

 

that would be a B16a head, likely from a JDM 92-95 Civic SiR

 

bah
SiR-2 doesnt mean pr3-2
SiR-2 is P30
pr3-2 head is a b16a1
Just look right above ur exaust manafold above the number 4 cyninder, ull see a date that is stamped on the head between 88 and 90
hope that helps

 

Check your post in the Hybrid forum......

 

I'm non-follower of the 'PR3-2, or PR3-???' markings on a B16A head.
Any b-series head with a 'PR3' marking/stamp/characterstic of any kind IS a B16A head. A type-R head is a B16A head, ported, it has the same PR3-xx markings as well.

Now, the way to tell a newer B16A head from an older on is buy looking here:



even though the '30' marking is on the 92+ heads, they still have the same 'pr3-xx' markings as well.

older B16A heads do not have this '30' marking at all near the VTEC solenoid area.

On the front left side of the head you will see circles with numbers inside them. The first one (from the left) will tell you the year of the head. Since you already know that it is a b16a head, once you know what year it is from, it will be easy to decipher what car it would have come from.

 

thanks guys
