Best Aluminum Heads

cs19 does Dart still make 320's they were not listed on their website. Also are you saying the Pro1's are better than the 320's 360's? Flowwise out of the box?

I found this website which shows comparative flow rates for different makes. Just for reference only: www.centuryperformance.com/afr/AFR BBC.pdf

My dart 355cnc's head flowed 415cfm at .800 lift and 303 on the exhaust out of the box.I had the heads flowed at alan johnson racing.I hear people talk about buying them bare and set them up for a boat.I have plenty of freinds that have bought pro-1's complete and ran the piss out of them on a boat with no problems.My heads came complete but with a bigger o.d. triple spring installed and i turn my motor 7,000 plus with no issues.My buddy has ran the 345 pro-1's on 572"blower motor in a 21 daytona for 3 seasons with no problems.He just pulled motor and installed different valves but the ones from dart where still good.

I think I'm going to end up with 325 Pro 1s with the 2.30 intake. 468 mechanical roller well over 7000rpm. I'm buying bare heads. Then when I go bigger cubes I can have them CNC to a bigger runner.

I tried to post a link but it did not work. Check with these guys before you buy those Darts.LVJET would know more about them, he has a set.I do hear good things about them.
