B18a B18b head stamp difference

Are they both PR4-xx? Is the date stamp the only way to tell?

I am going to get my car BAR reffed and want to get the right stuff.

The A1 head is stamped PR4 while the B1 head is stamped P75, I believe.

integra ls OBD 1 = PR4
integra ls OBD 2 = P75
crv (most b20s) = P75 (yes the same head as the integra ls OBD2)
(the other 0.01%) = P8R
