Brodix dragonslayer 320cc

Does anyone have any experience with these heads? Any actual impressions of there "as cast" they seem very cheap and wondering if anyone has any first hand experience with them?
I truly appreciate your knowledge

Re: Brodix dragonslayer 320cc

Looks like complete heads start at $934.20 each ($1868.40 per pair) and go up to $1310.85 each. That's not exactly cheap considering some of the offshore heads available. Sorry but I have no experience with these heads.

Best you talk to Mike Lewis (wolfplace), Mark Jones (VortecPro) or Chris Straub (cstraub). Any one of them will be able to answer your questions and give you sound advice based on your build requirements and intended use.

Re: Brodix dragonslayer 320cc

They are still a 26 deg. head, but seem to be a pretty good bang for the buck.

I would contact Eric. He very likely has experience with that head.

or there is quite a bit of basic information on the Brodix website.

The ProMaxx is a much better head especially for the price.

Re: Brodix dragonslayer 320cc

PS "Dragonslayer" is slang for offshore, so do compare them to OTHER offshore castings.

Out of the box????? I have my doubts.
Have you flowed an as delivered ProMaxx 317 assembled head?
Don't get me wrong, I know that once you rework the heads they are good to go but just how good are they if a person were to buy a complete assembly?

Yes. Several sets. I probably flowed one of, if not the first set in the country. Flowed them, weighed them, measured them and Rockwell tested them.
Flow numbers aren't everything but the ProMaxx heads flow as good if not better, they have a better chamber design, much better casting, 24* instead of 26...shall I go on?

I can just state that I'm impressed with the casting as well, it's quite nice. I'm unimpressed with only being able to use a 1017-1 head gasket. The other gaskets I tried including the Cometic head gasket for a 4.600 bore and it hung in the chamber. Kind of odd I think. I am unimpressed with the valve job and where the seats are in relationship to the bowls.
That's just my novice impression. I am simply disappointed that I'm not comfortable using this head as it was shipped. No flow numbers aren't everything but good quality of a whole product as is. I hate buying something twice.

Maybe I'm a little slow here, but you're joking, right? Offshore? Not according to brodix. They claim that they're made right across the street from thier office. That's what their salesmen say anyway.

I was considering their BBC dragon slayer 365cc heads for my 632cid engine. One thing that surprised me was their salesman told me, (I've spoken to three of them so far) that on their assembled heads, they don't install valve seals on the exhaust valves. Only on the intake. He claimed they've been doing it that way for 20 years since it helps keep the exhaust guides and valves lubricated and cool during use at the drag strip. IDK enough about that topic to say if that's bad or good.

Gene,

I believe these are Brodix attempt to offer a US casting at a price point to compete against the offshore castings.

Oh, now I get what Gene meant. IN other words, "Dragon" is supposed to imply China. OK, I was a little slow on that, but that doesn't have to mean that they're casted nor made with parts from overseas.

Re: Brodix dragonslayer 320cc

The dragon slayer heads are a fairly new offering from Brodix, and the main point of the savings with them is that they're taken from a full CNC ported BB-2x Brodix head, and were casted from that CNC model, and are supposed to offer the flow characteristics of the BB-2X CNC does, but without the xtra CNC machine work that would add an additional cost to the customer. That's the main benefit of the BBC Dragon slayer head. You're getting a better flowing head than there other as cast heads flow, but at the same price as an out of the box as cast head, along with better flow numbers. Supposed to be the best of both worlds in that sense.

Another thing that some of their saleman didn't even know until today: (long story) is that the Dragon Slayer is now their only BBC 26 degree head that comes standard with their upgraded Manganese/bronze valve guides. All thier other BBC 26 and 24 deg heads have the phospherous/bronze guides, and require a special order to be upgraded to the Manganese/bronze

Re: Brodix dragonslayer 320cc

Billy, that was a silly "knee-jerk"comment i ought have left unsaid,but yes, an odd choice of words as others have used it to define their offshore parts. Carry on!
