Re: Best Aluminum heads
KAAMA--
That is great info about detonation. I have to agree with your thoughts on the aluminum heads and detonation. I wanted to change to aluminum heads so that I could gain more power by buying Brodix heads that were already CNC ported with good valves ready to bolt on. Since I am going to be running superchargers at fairly high boost, I think I must definitely do better research about going with aluminum heads.The fact that detonation could happen pretty easily is a factor. I guess I could send out the cast iron ones and have them extrude honed to open them up. Oh well--back to the drawing board.

Chris,
Can you sell me on it being an advantage to have aluminum over cast for what I am doing??
Thanks,
Dave

Re: Best Aluminum heads
Dave,
Sales Job. You go with iron. Have them ported for around $1K. So you have $3K in each set. You buy gas at the dock. Just so happens octane is not what is posted and your torch the iron head. You now have to get 1 head get it ported to match other head. . .this would take around 3 to 4 weeks. Now do want to explain to the wife/girlfriend why she just missed 3 or 4 weekends of boating. Someone once posted on one of these sites. . .women don't care how fast a boat goes, they just care it goes.
Aluminum head. Remove head, take to weld shop, repair. Put head back on. About a week. No explaining to wife or girlfriend. PRICELESS!!!!
I would call RMbuilder and get him to price you a "package deal".

I am sure there are exceptions to the rule, but most likely, if you detonate a cast iron head it won't hurt the casting like it will with aluminum heads---cuz once they start to go, they go quickly. I hope I said all this correctly. Perhaps someone else can chime in here as well.

Re: Best Aluminum heads
JCPERF, I was down @ cobra power a few weeks ago and randy told me he ran a set of the new dart 18* cnc heads and a set of his brodixs heads he ports in house, back to back on the dyno and made 30 + more hp with the brodix heads. ratman

Re: Best Aluminum heads
I was considering the profilers but heard the conventional model requires alot of work to flow like yours do. And I didn't want to go to the big chief model.$$$$$$

Profilers are the CATS AZZ!! The 12 degree compares to only Big Chiefs. (There even better) If your running big Cubes, Top notch Rotating Assembly's. They will make incredible power well into 8500 rpm,s. Period.
Here is a comparable profiler to the heads mentioned in this poll.
Take this head and massage it a little. bolt them on and HOLD ON!!!!

The heads mentioned in this pole are all pretty good for the intended application.
The ones that make the real power are Chiefs or Profilers.
H'm, I wonder what heads do guys like Mike at Sterling or Rod at RaceCrafters use?
Just my 02.
