As said, make sure you fit the efficient like for like STi v.6 heads (NOT the MY00 WRX ones).

Straight fit and will be the same as what's fitted to your P1. These heads can breathe enough for well over 500bhp (should you ever forge the motor/remap, etc).......

Your P1 is based on a version 5 STI, but the engine is the same as the version 6 STI, your car is also an MY00 (2000 year), dont go off the registration year, order the wrong part and your stuffed as the engines are different between 2000 and 2001 cars.
Basically any 1999 or 2000 model year STI engine has the same heads.

It might be worth having a search around on here:

99/00 Head casings are the same regardless of WRX, STI Uk. The cams and valve train is what sets them apart. If you’re replacing just one head make sure the new head height is measure and matched to the existing taking into account the current skim which it will need, or you may find yourself having a different CR for each bank.

As I said before, a P1 is based on a version 5 STI, the version 6 heads will fit as they are the same (you will find the version 5 STI has the same lch007 code).

I think you may have mis-read the code on your P1 heads - they should be LHC for the left hand head and RHC for the right hand head. The numbers after the letters will range from 004 to 010 IIRC but are basically the same head casting.

Most of these heads have cracks radiating out from the spark plug thread in the combustion chamber and is caused by the spark plug being 'shy' of the last 2 or 3 threads in the head when tight - can be prevented by indexing/machining the spark plug mating face in the head so the spark plug comes through the last couple of threads.
