pr4-4

[fernando_dc2]

I'm wondering why my head on my integra says that ithought it should be p75? Is it normal to have pr4-4 stamped instead of the p75? I searched in goggle but didn't really find a answer

That's a B18B head code for 96-99 LS/GS/RS Interga from what I can find.

You are correct. Its from a B18B

Whether its a PR4 or P75, they are the same casting.
