I'd really like to talk to someone that's already done this before I go through with building up one of these heads. P8Rs seem like they have a lot of potential, and if anyone has any actual experience with building one up (porting, cams, valvetrain, etc.), I'd really like to know what kind of results I can expect.

I'm sure hope SOMEbody on this forum has some real experience with these heads.

 

I can't help you, but I would love to see a 'worked over' P8R head on a sleeved 2.0 B18a/b or B20 with 404's and raised compression. Should make some good numbers.
