Which head is better to fully build p72 or pr3?
i have 2 heads, one is a 99 gsr head and the other is a 99 b16 head. Which one would be better for me to fully build, i am aiming for 500+hp. i am thinking that fully building a head would make no difference if its a gsr or b16, but i could be wrong can i get some help with this?

To answer your question the B16 head flows more CFM, but a good reason to build a head is for reving the motor higher.

IMO BUILD ONE AND KEEP THE OTHER AS SPARE.

Thats also the thing i have an extra ls block that i can use for one of the other heads... i just dont know which one i want to fully build and put on my gsr block. the ls/vtec swap will be for my gf when i get her a civic. So i should build the b16 right?

PLEASE DO NOT LISTEN TO ANY OF THESE CORNBALLS WHO TELL YOU THAT BUILDING A HEAD IS USELESS.
I WAS ONE OF THOSE PEOPLE WHO LISTENED TO THE " BUILDING A HEAD IS A WASTE OF MONEY " PEOPLE AND GUESS WHAT?
I DROPPED A ******* VALVE WHILE BOOSTING THE CAR AND IT WAS GAME OVER....NOW I NEED A NEW HEAD, PISTONS, SLEEVES AND CRANK....DO YOURSELF A FAVOR AND BUILD THAT HEAD.
YOU DO NOT NEED TO PORT AND POLISH, BUT ATLEAST GET THE VALAVE TRAIN.
LASKEY RACING HAS A GOOD SUPERTECH VALAVE TRAIN DEAL.

If you are not going to send it out to be ported then run either, won't make much of a difference. If you are going to have it ported either now or in the future ask the porter you think you might send it to. Each cylinder head guy has a favorite. My personal choice is the gsr head due to the steeper ports.

Well if it's that hard of a decision, then just leave your gsr engine along, and put the b16 head on the ls block and go from there......
