Hemi heads

Post  stanger68 on March 5th 2019, 11:14 pm

Why are all hemi heads so expensive? No matter who makes them and for what brand engine.  But namely the kasse boss 9. for example 340cc 18 bolt TFS  A heads $2800 per pair. P51's: $2700 pr.; SR 71's: $3000 pr.  Boss 9: $4350 pr. ; A441 $3000 each bare list goes on and on. There isn't that much more metal in them. I'm pretty sure i'm not the only one who would buy a set if the price was a little closer to that of a wedge head so the supply and demand theory doesn't really explain it.

With all that said I do give jon a solid A+ for effort in giving us something that is at least obtainable to the average guy.

Used A heads are probly the best buy out there and for new heads P51s aren't far behind.

A few years back someone had Carrol Carter quote IHRA prostock hemi heads and intake at $28,000 out the door, ready to bolt on.
The head castings and guides and seats would be $10,000 by themselves.

I assume the one off races stuff is expensive because of the raw material costs and the amount of labor needed to whittle down a big block of aluminum. When it comes to cast heads (any cast parts) I have never understood it either. After the initial investment of molds is done it boils down to cost per unit. The more units you make the the lower the cost of the mold gets per unit. I can understand if they are rare low volume parts then the cost per unit would be high but damn it man, everyone I know would like a set of Boss 9 heads so make a shit ton and lower the cost per unit and more people will buy them. Very Happy

The simple "supply and demand" principle of capitalism.

Because they are more scarce and not many ... covering the cost of making them becomes more to the end user.

Lower quantity means the pattern and development cost must be amortized by higher price per head. Also the hemi heads have higher pattern and machining costs due to more complex cores, compound valve angles, larger head size, etc.

Last time I checked the TM Boss 9 heads were $3900 set bare.

How about looking at the complexity of the casting ( cha ching) and the additional amount of machining time. Time is money.

Yes, that's delivered C&C ported.

That alone is worth $$, Some don't get it

What is so complex about the casting? Don’t all BBF heads have compound valve angles? I’m not bitching. I’m just asking. I estimate commercial and industrial construction projects for a living so I know a thing or 2 about cost and markup. Maybe my ignorance is I’ve never had a boss head in my hand. It just doesn’t seem like there’s any more work to produce a Boss 9 head versus a TFS A head. When I built my 557 I would’ve easily chosen the Kaase boss 9 head over the TFS A head had the price been the same.

As far as the Boss-to-A-head price comparo, or Edelbrock comparison or whatever: Those heads are (or have been) cast at least 1000 pieces at a time, and possibly thousands at a time in some cases, which dramatically reduces costs aaaall the way down the manufacturing line.  As much as you want a set of Boss heads for cheap, a cylinder head manufacturer is not going to sell 500 sets or more Boss 429 heads in a year and recoup the initial investment, let alone turn a profit. There simply is not that kind of demand for them I don't care what anyone says.

Are the TM Boss heads American made?, or are they the Ebay Chinese knock-off's that have hit the market?

Tod Miller's heads are made in America.

They are real BOSS architecture using Boss 429 production type rocker arms.

Post  hbstang on March 12th 2019, 11:21 pm

the cool factor is a big part of the boss heads,but just like anything else it takes cubic dollars to make it fast.low production numbers keeps cost high,and you have to buy the valve covers,$700 plus,the intake$ 700 plus,and rockers ,$1600 plus.so it adds up.for the money,it looks like the sr-71 heads will do very well.1 boss engine is never enough!
