Sad but true. lets hope it won't happen again!

A big, tall head with very long valves, as mentioned. Should provide considerable material for port work without breakthrough. The valve length is close to what we run and we haven't experienced any problems with our stuff. Long valve guides, light valves, really thick large diameter pushrods, and killer springs all contribute to a very stable valve train. The inline head design, while a compromise in many areas, produces a very stable valve train at high RPM's. I don't feel stud mounted valve gear is optimum on any head utilizing the parts I mention above. You would be asking an awful lot of the pivot points, studs and aluminum rocker arms.

My warp - 6 heads are advertised 460 cfm as cast nothing but a gasket match . My 541 dynoed 1025 at 7500 rpm . I was quite impressed . They are back at Kauffmans shop to be cnc ported in preparation for the new aluminum block 535 . Don't know it I will dyno this spring or fall once race saeson is here it'll hit the track

Pretty DARN good for a MILD engine set-up!

I thought Warp6 was a billet head?

Yes & No it started off as a Billet then KRE casted it! Right now its the Best flowing head out there! Also the Quickest/FASTEST right now.......but that could change Boss Birds RA5 are charging hard!!

It would be cool to see what Marcella could with these Super Wedge heads.

True, but "cfms" are not cfms. Some peoples are better than others. Mikes E heads went 414 and made 1218 HP. I tried but could not get them. So I went for 404cfm heads by Gabby. Great heads, he was the first to get 1000HP NA with E heads, knows what he is doing. They made right at 1000 HP, depending on dyno. Sure, it was with NO2 cam and a heavily ported Victor vs a heavily ported BOP. AND 18-1 CR but two HUNDRED HP is a lot of HP.
I truly believe he has a gift. Can look at a port, runner and know where material needs to be removed to fill the cylinder.
If you look at just cfms those 450 cfm HPs should have made 1300HP NA, But its not about that . I just think its nuts that a "little" E head with factory steel guides made that kind of power NA.
BTW, High Port started off as a billet too.

No there not the best flowing head out there.

The only reason it's fast is its light.

not the first to make 1000HP NA w E heads: 900+ RWHP in 2007 John Bailey/Neal Owens/Slawko heads

450cfm will NOT give you 1300hp n/a on top of a 565" Pontiac. Not even close.

[Tom Vaught]

Thank You John Langer, for the post. I did the math on the numbers this morning and was a bit surprised at how efficient
the SUPER WEDGE heads were (making that much Horsepower) for EACH of those 450 cfm of air. Thanks for the clarification.

Same as 414 CFM won't make 1200 HP N/A?

It won't... you need around 460-480 cfm to make 1200 hp na on a 565" Pontiac. I can say I have a dyno sheet that says I make 1500hp but if I don't run the number did I really make 1500 hp?

[johnta1]

Agree 100%

[GTO Dan]

Depending on the price point, that head could be a very good option.

Normal rule of thumb is" (from a old super flow caclulation):

CFM times 2 and then a efficiency multiplier for a very good port.

So we do 480 cfm times 2 = 960 HP (or 2 hp per cfm) not too hard to do.
Then we multiply by the efficiency factor (1.1, 1.15, 2.0, 2.5, etc)
So in this case using Langer's number for CFM we get 2 times 480 cfm = 960 HP TIMES 1.25 efficiency factor and we get 1200 horsepower.

If we do the same calculation again for the 1300 hp number:
we get 2 times 480 cfm = 960 HP TIMES 1.35 we get slightly under 1300 hp.
1.35 is a bit of a stretch for typical engine.
If we do the same calculation again for the 1300 hp number:

we get 2 times 414 cfm = 828 HP TIMES 1.45 (NOT A TYPO) we get slightly over 1200 hp. ( 1200.6) You have to have a really good set-up to generate that type of multiplier number.

I tend to go with Langer's statement.
