Hello I am looking to go to aluminum heads on my bbf , was wondering if anyone had any that they wouldn't mind selling.
I know of some ported and assembled A429 heads. Call directly if interested.
I am on the look out for edelbrock preformer rpm heads...the only none cobra jet style head that will just bolt on to my current setup.
When it comes to OEM valve layout heads and what will fit your current pistons, the TFS Street Strip heads are superior to the Edelbrock heads, and out of the box they need almost no porting whatsoever as compared to the Edelbrocks.
The iron heads I have now are big valve, scj intake and exhuast sized ports, with bowl work . They flow 319cfm on the intake and about 190 on the exhuast...the edelbrock preformer rpm heads with bolt on. And work well with a bit of porting and bowl work as well .
It really depends on the rest of your engine combination, but just swapping from ported D0VE heads to aftermarket aluminum heads such as Edelbrock (etc) might not result in a power gain that justifies your 4-figure expense....especially in a jet boat where a good deal of horsepower gain is necessary to see just a few hundred rpm increase.
I saw a engine builder make 700+hp from a similar set up to mine with edelbrock heads so they will most likely be the one I get . I set my current heads up so I can use all the valves, springs , push rods everything on a set of rpm heads, so I thinks that's the way I am leaning.
Just a thought: you might be able to make 700+ hp with a 557 simply by properly porting your D0VE heads, and for far less cost than aluminum heads. Again, it depends on the rest of your engine combo.
...it's a forged 557 single 1050 on a victor. I think there is a a good enough performance gain by going to alum heads that flow better .
Flow isn't everything, and is the last ting you should look at when deciding on cylinder heads--I've seen "lesser" flowing heads make more power on a dyno than the higher flow number heads that were changed out. But swap to procomps over your ported D0VEs? Your engine will probably lose power across its entire rpm range, more and more as rpm increases. I am not being facetious.
