"Boss 9" is the particular name that Kaase has put on his own brand aftermarket production style heads; I also understood you to be a 429 boss engine connoisseur and would know that fact.

If the question is can they make more power than a wedge head, the answer is yes in the right hands with the right combination they will. Whether they make enough to justify the cost, that depends on the individual. There are a number of aftermarket Boss 9 heads out there and can be used to make power. 600+ inches and with the right combo can make 4 digit power N/A fairly easy if thats what your asking. I would talk to Boss429(Circle R ) if thats the direction you really want to go.

Which wedge head??? Which hemi head??? The point is that some hemi heads can not make as much power as some of the wedge heads we have on the market,,,,and then again vice-versa. Some hemi heads will make more power than some of the wedge heads we have on the market. There is an over-lapping of their capabilities.

Thanks for clarifying which heads. I have ported and flowed all three of the ones you have mentioned. I believe that a 600 CID TFS A-460 headed engine, with properly ported and flowed heads will make slightly more horsepower and torque than a equally prepared Kaase Boss Nine headed 600 CID engine. Maybe the best person to ask is Jon himself.

Likewise I believe that a 600 CID FRPP C-460 headed engine with ported and flowed heads, would well exceed an equally built 600 CID Boss Nine headed engine, in terms of torque and horsepower.

IMO the Factory Style Boss 429 heads (Kaase Repops) are every bit an equale to A460's when prepped properly and the A441 and B441 Stuff (Race Stuff) is ahead of the C460 stuff in the right application.

Only issue I see with the Ford Hemi Stuff is Packaging and Cost. The Wedge stuff is smaller and cheaper.

But again not every application benifits from the same things.

NOT GREAT COMPARISSON

It is probably not the best to be comparing a street or shall we call it a conventional head to the built for racing A and C Head . In Mr Kasse own testing when he built the head they were slightly stronger horspower wise to the simaler SuperCobra jet and P51. I think that it would be better to compare the B441 to the A and C heads but that is just my opinion.I guess it all comes down to the intended use and is a maxed out street HEMI head going to get you what you want powerwise and no more will be needed later on. And yes they do look very good compared to most wedge heads. JOHN

I agree 100%. If you got the cash, and want a boss headed motor they are out there and chances are if prepared correctly you WILL NOT be dissappointed. $$vs. horsepower thats a individual choice. I have never personally seen a A460 head around 600 inch make 1350+hp and 1000+ tq N/A, I have seen it with a A441 hemi.

How do you think the Boss9 would work with a blown injected on alky. engine?

Personally, I think it would work well ... that's one of the applications where the hemi shines; (as long as nitrous isn't involved).

the boss nine heads arent the top of the line RACE Ford Hemi head. The top of the line boss hemi head is capable of exceeding what an "A" head or "C" wedge head is capable of.

However if you are talking aobut something closer to a production head then there are WEDGE heads that can outperform these heads.

I am still not clear EVEN after you said "boss nine" which HEMI style heads you are refering to. I am not sure you know that Boss nine does not cover the entire spectrum of Ford Hemi heads. no offense meant. Specifically do you mean the Jon K heads?

IMO if you are going to suffer the expense of a blown motor, youd be handcuffing it by sticking wedge heads on it.
thats not to say that it wont work, a blown wedge can make a ton of power, just wont out dyno a hemi head motor.

This is not a maxium effort just looking to make 1200 - 1400 hp. The heads would be more for looks than hp.

Match race I guess you would say, I am going to run with the Great Lakes Nostalgia Funny Cars circut. They are mostly BBC chey engine cars with a few hemis . Although it is not index racing if you run faster than 7 flat you get afine. Most of the cars run 7.20 - 7.50 range so horse power is not a problem.

TM Enterprises makes a nice Boss 429 reproduction-style head with some upgrades. Their head is more of a reproduction-style head while Kaase's is more changed from the original in the interest of power enhancements.

Haha! CACKLE, not "crackle." geek

N/FC is more of an exhibition class these days, and while the 4.900" bore spacing rule is being applied (I believe that to be erroneous on the part of NHRA but I don't know for sure) a suprising number of us are still moving forward with a 385 Series powered N/FC car in the belief that N.H.R.A. will alllow the cars to run as they originally were allowed back in the day.

And if they don't let the 385-Powered N/FC cars run, there is a little-known class to run these cars, ya know. Wink
