Message: [QUOTE="psduser1, post: 1548759, member: 735"] I gotta disagree.:shrug: Even simple head port/polish will lower your observed boost pressure-meaning less airflow restriction. Bonus, if you can run a die grinder with a flapper wheel, it's easy and quick to do without paying the big money. I'm not saying that the home job is equal to a cnc port and polish by any means, but it's pretty easy to gasket match and polish runners. That vs a 1000$ cam? No contest in my mind. At 500 hp, it's a no brainer. At 900 hp, well that's a different animal. P/p at 500 hp lowers back pressure, boost and could very easily improve the torque and horsepower curve. [/QUOTE]
