Best Aluminum heads
 

I am in the market for some Aluminum heads for my 502's I am building up. Who do you think has the best heads. Right now I am leaning towards Brodix heads. I am staying with stock compression, a mild cam and Whipples at 8 PSI of intercooled boost. Looking to hit 750 HP per motor.

There is no best head, just good combinations. You could spend $15K on heads and if the the combo is not a matched system all you will end up with is a lot of money spent on something that doesn't run.

About any will make 750hp with that setup.Would you be interested in a used set of Brodix 2.I am going to buy some new CNC ones. These made 730 hp on n/a 598's with hyd cams and pump gas.

from a noob - besides weight, what's the benefit of aluminum -vs- iron?

Re: Best Aluminum heads
 

Heat dissipation. smoother air through the transfer ports. Will overheat faster and expand faster than cast and leave you with cool looking boat anchors.

Re: Best Aluminum heads
 

If you're buying new ones, go with the Profilers. They're really not any more $$$ than anyother of the CNC'd ones. With a little bit of massaging by the right person, they WILL out flow all the others. If you're lookin to save some $$$, just go with good used ones.
Remember.....You get what you pay for, and sometimes that great deal will cost you more in the longrun. Just my $.02

Probably I would go with AFR heads. They will produce bigger numbers with the right combination to go with them.

I have no complaints with Edelbrock marine heads. They make good power in my set-up.

Re: Best Aluminum heads
 

The new Dart 18 degree chevy head hands down the best head in that category.

One of the pro & cons of aluminum vs cast iron is that with the aluminum heads you can get away with running a higher comp ratio, and still not get into detonation, whereas the cast iron heads you cannot. Here's the flip side---I am not a metals guy, but once you are into detonation with aluminum heads they tend to melt much faster vs cast iron heads. 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.
