Cylinder head restrictions for rally?
I need to rebuild the cylinder heads on my '02 wrx. I figured it'd be a good time to port and polish them along with a few other minor mods. I want to start running some west coast rallies. Is there any limitations on what I can do to my cylinder heads? I figured I'd be in the PGT class. I'm having difficulties finding info on this. Any help would be appreciated. Thanks.
