I have been looking into a few options for CNC ported aluminum heads to offer customers. I have a few questions for you guys to kind of steer me n a direction If you were looking for,say a standard port small block head that had been CNC ported,what would sway you one way or another? If a casting were from a USA based company and flow numbers were the same or similar to an imported casting but the cost was higher,which would you choose??? If I offered USA based castings,but the flow numbers were slightly less than an advertisement showed for somebody else's foreign based casting but cost less which way would you go ? If I offered a similar foreign based casting with some flow numbers that were less than someone else advertised,but were significantly less expensive,would that be your choice ?? Basically,is cost,advertised flow numbers,,or country of origin you main priority? Keep in mind that all flow benches read a little different . And most advertised numbers tend to be generous. Thanks for any real opinions,but please don't just jump on an anti Chinese bandwagon if you have no interest in the main subject here. Keith

Since you are trying to gauge the market, how about listing the current products and target use for each? I guess you shouldn't include names of the heads or vendors to avoid a However, any input for intended RPM, size, and typical use would help define the markets and narrow what people want/need. EXAMPLE: 340-360 max RPM 5500, street (do you even need ported aftermarket heads?) 340-360 max RPM 7000, street/strip 340-360 Strip only Stroker (400-420) max RPM 5500, street Stroker (400-420) max RPM 7000, street/strip Stroker (400-420) Strip only Bigger stroke, more RPM Also lay out what valvetrain requirements are needed for each proposed head, so full cost can be considered. An economical head that requires space program priced cam/lifters/pushrods/rockers/springs is not a bargain.

Just went throughnt his scenario and ended up buying a set of CNC ported Edelbrock magnums from Hughes. Why you ask? Edelbrock is a reputable US company. Hughes is a reputable US company that I have used in the past - and got to deal directly with Dave - what a treat! Probably paid a little more than some others for the comfort level. I was able to use some of my existing Magnum valve train / head studs over again. Their stated flow #'s were with in 10% of the highest and lowest #'s available for this style head. I knew who cast the heads and aluminum used in their castings was a known quantity - not that I am a metallurgist . Options available included inserted LA intake manifold bolt pattern.

you could look at the boarded up windows in Detroit for some answers. If we had racers who could afford to race they would prefer American quality... welfare check can't buy very many parts these days.

Basically what I am considering offering will be Edelbrock castings for small and big block both. The problems I am looking into are competitive pricing compared to imported castings with a similar level of work. There are some decent quality imported castings which look to be direct copies of Edelbrock heads as far as appearance goes. The other issues come from several places that advertise flow numbers that are not being seen on any one else's bench. I know of a few. I would plan on listing fairly realistic flow numbers,possibly runner cc's etc. Depending on what people want. I may just buy imported heads and call them my "Quicktree Special" Keith

Modern Muscle does cnc porting of your Gen III hemi heads. They have a deal where you strip your heads, get them cleaned and then send them to them. They will run their program on them for $599.99 and ship them back. That is a good deal in my book for most of us tight a$$ Mopar folks in my book. Then you can have your local guy, or you, do the valve job and assemble.
Mopar to the bone!!!

For me it is flow/power potential, then cost, with where they are being made last priority...Sure I prefer to buy domestic products over foreign, BUT, if the heads are being bought bare overseas and the CNC work and setting them up is done here, that is enough to assure me the quality is up to snuff.
As for flow numbers, I agree that they should not be the only selling point for heads as is often used....What I really think it missing in the SB mopar world is a set of heads (or more than one set from different manufacturers like the ford and chevy guys have), that is affordable, supports good performance and is not an all out race piece in terms of price and performance.
That said, these new foreign heads that have hit our sb market really seem to be advertised as a great product, but im not sure the performance matches with so little people able to get their hands on them, and then some reporting they don't flow what they should on a bench...really makes you wonder who you can trust.

guys here is what happens, an American company does all the research and testing to bring a product to you. then someone sends them over seas to be copied.you buy those and eventually put that company out of business. in the end you end up with a bunch of chinese crap and no more American companies.then blame it on someone else.
Beating a dead horse! There isnt one person on this board who doesnt own something chinese made or at least imported. Fact of the matter is, if you want to keep your doors open for more than a year you better offer something the majority can afford.

I'll avoid the whole ethics issue of import castings which are simply "clones" of domestic R&D efforts and, instead, suggest STRONGLY that any initiative on your part based on using import castings needs to start with a thorough inspection & evaluation of those castings.
From what I've seen w/ the Pr*c*mp BB Victor "clone" casting I've posted about recently (porting work I've done while using one as a substitute for an actual Edelbrock casting), it has some issues that are not going to be "fixed" by simply applying a CNC porting program to it. I can't speak to the quality of the casting material / metalurgy(sp?), which might be perfectly acceptable, nor the reliability of the valve seat installation from the manufacturer, if replacing them is not part of the plan.
As far as what influences my own cylinder head purchases, I DO take into account the origin and general reputation for QC and/or known issues before even considering the advertised flow #s, runner volumes, etc. I may be in the minority based on the folks who post about budget concerns driving everything.
If they're only offered as a "one size fits all" version, having proven dyno & track results for typical combinations applicable to those heads would be extremely helpful in gauging their effectiveness, as opposed to being sold simply on the merits of their flowbench results.
If you're not able to offer a product that is filling a void in the market and are simply providing "just another ported head", IMO your success will be tied to marketing (e.g. advertised flow #s, regardless of other pertinent aspects of the head's design) and / or price, since some people seem unable to look beyond the initial purchase price, regardless of what the long-term cost-of-ownership implications are (e.g. paying additional $ to fix flaws, reliability issues that arise that result in additional repair expenses, etc).

All these companies are at a big stand still right now. I talked to the guys at Trick Flow and we were throwing some suggestion at them and they were all ears. Brian said he talked to them too but i don't see them moving on a project like this till the economy straightens out.
