Like a chevelle running a 540, with a 6cyl radiator, autozone water pump, idking for 30 minutes on a 90 degree day with 220-230 deg water temps nearly melting the plastics off things under the hood.

For the record, I didn't debate what was said. To restate what I wrote, is that you don't see it often. If we did see iron being used all the time, there would be iron heads on all marine engines but that's simply not factual.

At the end of the day, do what works best for you.

I was not debating whether an aluminum head makes more power or not. It's a quote from an article and the reference link was included.

That is what I said (Identical). Same head design, different material. Now we're splitting hairs.

Agreed.
I certainly didnt buy iron heads hoping to make more power with thier heat retentitve attributes. I bought them because i simply wanted some heads that will last, because even in freshwater, aluminum corrodes. I also wanted a good head design, that flowed well, and a cost package, that would allow me to have a guy tailor them for my application.

As for power, i would rather make it with airflow, rather jacking the compression and boost up thinking its ok because you have "aluminum ". I dont think its nearly that cut and dry.

I find these threads amusing. Joe spends his free time HELPING others on this site. You guys think JOE doesn't already know MORE about this topic then what's been posted here before the thread started....LOL

This site is mainly used by BUDGET members. If not we all would have million dollar offshore boats.

We all can agree that with money no object aluminum would be our first choice. So would a brand new Mystic, Skater or MTI. Screw buying these used boats, they are junk!

I really don't understand how this topic is being ARGUED in such a negative way????

With no hard FACTS to prove that an engine properly designed around iron heads will be JUNK compared to its aluminum brother, just marketing brainwashing.

Come on guys (aluminum head koolaid drinker pretend Rich ballers who can afford the best of the best on every single part purchase) try to be a little more positive when participating on here. Do you want more GOOD threads to entertain us and learn or not?

I write this with a smile no hard feelings. It's all in good fun!

I was simply responding to the quote, not trying to be argumentative.

Whenever someone poses a different opinion on here, it seems the bandwagon jumps in and supports their friends. This started out as a mutual discussion until folks started to throw stones because they did not agree. I for one did not throw the first stone and simply stated my experience but was challenged. Apparently I was not able to respond to the challenge?

I do not make millions and and sure are not a "rich baller". In fact, it's quite the contrary. I work hard for what I own and build and maintain everything I have so it's clearly not about money. I'll just sit in the corner while the few folks who are allowed to speak can hear themselves and everyone listen.

I have been on this site for a very long time and have been helping folks out for a very long time. Apparently that seems to have gone by the wayside. Things sure have changed over here.

See ya'll later.

This stuff is just a hobby for me. A fun hobby.

I didnt NEED to buy new heads. I am always up for trying something new. Maybe it will work out, maybe it wont. What I am not interested in, is building the oso crate engine special. We have all been trained aluminum AFR heads are where its at, and nothing else compares to them, performance wise, price wise, and so on. Are they a great head, absolutely. But is it possible something else is as good, for similar or same cost ?

When its all said and done, i will probably have nearly as much into these EQ heads , as a set of off the shelf AFR 325s. The difference will be, my heads will have my spring choice, my retainers, locks, locators, a marine specific valve job, and some porting. I'm sure they will perform better than the darts I had when it was all said and done. I was actually surprised to see how poor the exhaust flow was on my particular darts. The exhaust flow on the 345 irons flowed much much better. Same bench, same fixture, same day. The intake port was nothing to write home about.

Its all good discussion. Nothing more , nothing less. Lots of good input here. Theres nothing wrong with disagreeing, and or explaining why we disagree. Its winter , what else we going to talk about lol :)

Your blowing this all out of proportion bud! It's all good. Everyone's opinion matters and I am glad this thread is actually going smoothly....

Please keep posting my comment was not directed towards you or just this thread.

Maybe you didn't catch the last sentence in my post :drink:
