need info on pro 1's

[modracer0]

looking to buy a set of pro 1 platinum heads, cnc ported....wondering what price should you have to pay for the bare heads and what difference should we see being that we had a old set of pro 1's on it??? thanks for your help

The Platinum Pro 1 CNC heads retail for $1,069.23.
The difference in performance will vary based on what you are building, but if you are using old Pro-1s currently the CNC port plus the Platinum modifications will likely add up to some significant gains.

He is dead on here, the new stuff out of the box is worth about 5-10 and I have heard up to 20 hp better than the same cc head being used. CNC ported over otbox stuff is worth a ton more mostly about 40 hp. So if your coming off something wrong to something that is dead on, you could make as much as 50 better. If you have some pretty good heads now that have been done up well, look a little lower. The CNC stuff is not that much different to really see gains of what were are talking about. Its kinda like having the wrong carb and tune up and getting one from a professional that is killer dead on and your car picks up ½ second, but a carb that is dead on is hard pressed to get another one deader on!

I saw huge gains from my set of Pro 1's. My testing being apples and oranges though. I started with a set of Sportsman II heads and switched to the Dart heads with 215 runners and 2.05 valves. There were also alot of variables in my testing(bad valve job). But all in all, I am very happy with my Pro 1's. I think you will be too.............jmo Good Luck

Check out perfengine.com for some prices. I have seen some good prices there for the cnc stuff. I think it is around 2036 for a pair and free shipping. 608-836-3130 ask for Keith,he is a good guy.

Any prices advertised very low have their disavantages and they have short cuts. A good set of heads priced out correctly with the proper spring and retainer you would need it a varible. We can sell with anyone and most likely a little lower and help with shipping. So if your serious, give me a ring and let me know. Apples for Apples is the only way to really test and have proper data. I have not gotten around to testing the new head verses old one with just a head swap on the dyno. So the new heads do work a little better otbox. So the right size head for your engine will make way more power than old verses new. The trick is get the new head, right size, and then you have the best bang for the buck.

That is for the bare head..............like it comes from Dart. Sorry.......

No need to say sorry, if I could sell a complete head for that, I would order 10 sets!
