Default Help! 1.8l head info bp4w4-1 bp4w2-2 bp4w2-1??

Hello everyone,
What is the difference between these heads:BP5W-2, BP4W4-1, BP4W2-2, BP4W2-1?
OR IS THERE A SPREAD SHEET ON THE SPECIFICAITONS OF THESE HEADS?
OR ARE THESE HEADS ALL THE SAME, JUST DIFFERENT PRODUCTION DATES?

HELP????????????????????????

I do not believe there are any major differences. It may be date, or application as these BP engines were used in several vehicles.

Default Bp5w-2 is 1.8l head before 1999.

I got this from researching on google and other sites...

the difference my good sir, the 99 and up heads have raised and deeper angle head manifold ports and the intake side only uses solid lfter bucket shims. be safe and get the BP4w. its non VVT. also, no manifolds from 94-97 motors will fit this head
